About The Test
Purpose
The primary purpose of an MRI Shoulder Without Contrast is to provide clear and precise images of the various components of the shoulder, including:
- Bones (humerus, scapula, clavicle)
- Tendons (like the rotator cuff tendons)
- Ligaments
- Muscles
- Cartilage (including the labrum)
- Bursae
Key Highlights
- Non-invasive: The procedure does not involve any surgical incisions or injections of contrast material.
- Radiation-Free: Unlike X-rays or CT scans, MRI does not use ionizing radiation, making it a very safe imaging modality.
- Detailed Soft Tissue Imaging: MRI excels at visualizing soft tissues, providing information that is often not visible on other imaging tests like X-rays.
What is an MRI Shoulder Without Contrast?
How MRI Works
Magnetic Resonance Imaging (MRI) is a sophisticated diagnostic tool. Instead of radiation, it utilizes a strong magnetic field and radio waves. When you lie inside an MRI machine, these magnetic fields and radio waves interact with the protons in your body. A computer then processes the signals received from these interactions to generate highly detailed, multi-planar images – essentially, "slices" – of the targeted body part.
Non-Contrast Significance
For an MRI Shoulder Without Contrast, these images allow radiologists at Cadabams Diagnostics to meticulously examine the anatomy and detect abnormalities within your shoulder joint. The term "without contrast" is significant because it means no contrast agent (a special dye, usually gadolinium-based) is injected into your bloodstream or directly into the joint for this particular scan. While contrast can enhance certain features in some MRI studies, an MRI Shoulder Without Contrast is often sufficient and highly effective for diagnosing many common shoulder problems.
Types of MRI Shoulder Without Contrast
Imaging Sequences
When referring to "types" of MRI Shoulder Without Contrast, it's more accurate to discuss the different imaging sequences and planes used during a single comprehensive examination, rather than distinct categories of non-contrast scans. Radiologists use various MRI sequences, which are specific settings for the radiofrequency pulses and magnetic gradients, to highlight different tissue characteristics.
- T1-weighted images (T1W): These sequences are excellent for visualizing the general anatomy of the shoulder. Fat appears bright, while water-based fluids (like joint effusion or edema) appear darker. They provide good contrast between different soft tissues.
- T2-weighted images (T2W): In these sequences, fluid and inflammation appear bright. This makes T2W images highly sensitive for detecting joint effusions, bursitis, edema within bones or soft tissues, and tears (which often have associated fluid). Fat can also appear bright, so fat-suppression techniques are often used in conjunction.
- Proton Density-weighted images (PDW): These images provide a good balance, showing detailed anatomy and also being sensitive to fluid and cartilage abnormalities. PDW sequences are particularly useful for evaluating cartilage, tendons, and ligaments in the shoulder. Fat suppression may also be applied.
- Gradient Echo (GRE) sequences: These can be useful for looking at cartilage and fibrocartilage (like the labrum) and can also detect hemorrhage or calcification.
- Short Tau Inversion Recovery (STIR) or other fat-suppressed sequences: These sequences are very effective at suppressing the signal from fat, making fluid and inflammation (which are water-based) much more conspicuous. This is particularly helpful for identifying bone marrow edema, muscle injuries, and inflammatory processes.
Imaging Planes
To get a complete picture of the shoulder, images are typically acquired in multiple anatomical planes:
- Axial: Slices taken horizontally through the shoulder, like looking down from the head.
- Sagittal: Slices taken from side to side, dividing the shoulder into left and right portions.
- Coronal: Slices taken from front to back, dividing the shoulder into anterior and posterior portions.
List of Parameters
Rotator Cuff Tendons
- Assessment of the four rotator cuff tendons: supraspinatus, infraspinatus, subscapularis, and teres minor.
- Looking for: full-thickness tears, partial-thickness tears, tendinosis (degeneration), tendinitis (inflammation), calcific tendinopathy, and muscle atrophy associated with chronic tears.
Glenoid Labrum
- Evaluation of the fibrocartilaginous ring around the glenoid (shoulder socket).
- Looking for: tears (e.g., SLAP tears, Bankart lesions), detachment, degeneration, and associated paralabral cysts.
Joint Fluid or Bursal Fluid
- Assessing the amount of fluid within the glenohumeral joint (main shoulder joint) and various bursae (e.g., subacromial-subdeltoid bursa, subcoracoid bursa).
- Increased fluid can indicate inflammation, injury, or infection.
Subacromial or Internal Impingement
- Evaluating the space beneath the acromion (subacromial space) for narrowing.
- Looking for secondary signs such as bursitis, rotator cuff tendinopathy, or specific wear patterns on tendons that suggest impingement.
Articular Cartilage Health
- Assessing the thickness, surface regularity, and signal characteristics of the cartilage covering the humeral head and glenoid.
- Looking for: cartilage thinning, fissures, erosions, osteophytes (bone spurs), and subchondral bone changes indicative of osteoarthritis.
Bone Structures
- Examining the humerus, scapula (including the acromion and coracoid process), and clavicle.
- Looking for: occult fractures (not visible on X-ray), bone marrow edema (swelling), cysts, bone tumors or lesions, avascular necrosis, and degenerative changes like osteophytes.
Soft Tissues
- Evaluating the deltoid muscle and other muscles around the shoulder.
- Looking for: muscle tears, strains, atrophy, fatty infiltration, edema, or masses.
Ligaments and Joint Capsule
- Assessing the major ligaments (e.g., glenohumeral ligaments, coracoclavicular ligaments) and the joint capsule for tears, thickening, or laxity.
Biceps Tendon
- Evaluating the long head of the biceps tendon for tendinopathy, tears, or dislocation from its groove.
Acromioclavicular (AC) Joint
- Assessing for arthritis, distal clavicle osteolysis, or ligamentous injury.
Why This Test
Chronic Shoulder Pain
When shoulder pain persists despite initial treatments like rest, medication, or physical therapy, an MRI can provide a deeper look into the soft tissues and structures that might be causing the ongoing discomfort.
Acute Injuries
Following a fall, sports injury, or other trauma, an MRI Shoulder Without Contrast is invaluable for identifying specific tissue damage, such as rotator cuff tears, labral tears, ligament sprains, or subtle bone fractures that aren't apparent on X-rays.
Limited Range of Motion
If you experience symptoms like a stiff shoulder (e.g., "frozen shoulder" where MRI can show capsular thickening), painful clicking or popping, or a sensation of the shoulder "giving way" or feeling unstable, an MRI helps pinpoint the anatomical cause.
Pre-operative Planning
Surgeons often require an MRI Shoulder Without Contrast to get a detailed roadmap of the injury before performing procedures like rotator cuff repair, labral repair, or shoulder stabilization surgery. This helps them plan the surgical approach and anticipate potential challenges.
Monitoring Conditions
For individuals with diagnosed chronic shoulder conditions such as osteoarthritis or known rotator cuff pathology, periodic MRIs (though not always routine) might be used to monitor changes over time or assess the effectiveness of certain treatments, although clinical symptoms often guide this more frequently.
Inconclusive Findings
If an X-ray or ultrasound of the shoulder provides unclear results or doesn't fully explain the patient's symptoms, an MRI is often the next step due to its superior soft tissue detail.
Soft Tissue Masses
While contrast might be used if a tumor is highly suspected, a non-contrast MRI can often detect and broadly characterize soft tissue masses or cysts around the shoulder.
When and Who Needs to Take an MRI Shoulder Without Contrast?
Common Indications
Your doctor may recommend an MRI Shoulder Without Contrast if you are experiencing symptoms or conditions that require a detailed look at the soft tissues and bones of your shoulder. Understanding the non-contrast shoulder mri indications can help you appreciate why this test is being ordered.
- Persistent shoulder pain: Especially pain that hasn't improved with conservative treatments like rest, ice, and physical therapy.
- Suspected rotator cuff tears: This is one of the most common reasons for a shoulder MRI, helping to identify the location, size, and severity of tears in the tendons that stabilize the shoulder.
- Labral injuries: To detect tears or damage to the labrum, the cartilage ring that lines the shoulder socket (e.g., SLAP tears, Bankart lesions).
- Impingement syndrome: When tendons of the rotator cuff get compressed or "pinched" during shoulder movement.
- Tendonitis or tendinopathy: Inflammation or degeneration of shoulder tendons.
- Bursitis: Inflammation of the bursae, small fluid-filled sacs that cushion the shoulder joint.
- Arthritis complications: To assess the extent of joint damage, cartilage loss, and associated soft tissue changes in conditions like osteoarthritis or rheumatoid arthritis.
- Unexplained weakness or instability: If your shoulder feels weak, loose, or "gives way."
- Suspected occult fractures: Small bone fractures that may not be visible on an X-ray.
- Tumors or cysts: To evaluate soft tissue masses or bone lesions (though contrast might be used if a tumor is strongly suspected and needs further characterization).
Patient Groups
Individuals with acute sports injuries or trauma to the shoulder, those suffering from chronic shoulder conditions causing pain and limited mobility, patients with post-traumatic shoulder pain where X-rays are inconclusive or do not fully explain the symptoms, and individuals requiring pre-operative planning for shoulder surgery often benefit from an MRI Shoulder Without Contrast.
Benefits
Benefits of Taking the Test
### Detailed Soft Tissue Imaging This is a primary benefit. MRI excels in visualizing tendons, ligaments, muscles, cartilage, and bursae with remarkable clarity, far surpassing the capabilities of X-rays for these particular structures. This detail is crucial for identifying the exact nature and extent of an injury. ### Accurate Diagnosis By providing precise anatomical information, the **MRI Shoulder Without Contrast** helps your doctor make a more accurate diagnosis. A correct diagnosis is the cornerstone of an effective treatment plan, whether it involves physical therapy, medication, injections, or surgery. ### Non-Invasive Procedure The scan itself does not require any needles (for contrast injection) or surgical incisions. It’s a way to look inside your body without physically entering it. ### No Radiation Unlike X-rays and CT scans, MRI technology does not use ionizing radiation. This means there is no radiation exposure risk, making it a very safe imaging modality, even for repeated studies if necessary. ### No Contrast Risks Since no contrast dye is injected, you avoid any potential (though generally rare) risks associated with contrast media, such as allergic reactions or effects on kidney function in susceptible individuals. For many shoulder conditions, a non-contrast study provides all the necessary diagnostic information. ### Detect Subtle Abnormalities MRI's high resolution can often detect subtle injuries or early degenerative changes that might be missed by other imaging methods. ### Guide Surgical Decisions If surgery is being considered, the detailed information from an MRI helps the surgeon plan the procedure more effectively, potentially leading to better surgical outcomes.Illnesses Diagnosed with MRI Shoulder Without Contrast.
### Rotator Cuff Tears * **Partial-thickness tears:** Tears that do not go completely through the tendon. * **Full-thickness tears:** Tears that extend through the entire depth of the tendon. * MRI can also identify the specific tendon(s) involved, the size of the tear, and any associated tendon retraction or muscle atrophy. ### Labral Tears * Damage to the glenoid labrum (cartilage rim of the shoulder socket). * Examples include **SLAP tears** (Superior Labrum Anterior to Posterior) and **Bankart lesions** (associated with shoulder dislocations). ### Shoulder Impingement Syndrome While a clinical diagnosis, MRI can show underlying causes like subacromial bursitis, rotator cuff tendinopathy, or acromial spurring that contribute to impingement. ### Tendonitis and Tendinopathy * **Tendonitis:** Inflammation of a tendon (e.g., supraspinatus tendonitis, biceps tendonitis). * **Tendinopathy/Tendinosis:** Degeneration of a tendon, often chronic. ### Bursitis Inflammation of the bursae (fluid-filled sacs that reduce friction). Commonly diagnosed include subacromial bursitis and subdeltoid bursitis. ### Osteoarthritis and Other Degenerative Joint Diseases Characterized by cartilage loss, bone spurs (osteophytes), joint space narrowing, and subchondral cysts. ### Adhesive Capsulitis (Frozen Shoulder) While primarily a clinical diagnosis, MRI can show associated signs like thickening of the joint capsule and axillary recess, and rule out other pathologies. ### Occult Fractures or Bone Stress Injuries Small fractures or stress reactions in the bones of the shoulder (humerus, scapula, clavicle) that may not be visible on X-rays. Bone marrow edema is a key indicator. ### Avascular Necrosis (Osteonecrosis) Loss of blood supply to a portion of the bone (e.g., humeral head), leading to bone death. MRI is highly sensitive for early detection. ### Ganglion Cysts or Paralabral Cysts Fluid-filled sacs that can develop near joints or tendons, sometimes in association with labral tears. ### Muscle Strains or Tears Injuries to the muscles surrounding the shoulder joint, such as the deltoid or rotator cuff muscles. ### Ligament Injuries Sprains or tears of the shoulder ligaments, such as the glenohumeral ligaments or acromioclavicular ligaments.Preparing for test
Key Preparation Steps
- No Specific Dietary Restrictions: For an MRI Shoulder Without Contrast, you typically do not need to fast. You can eat, drink, and take your usual medications unless specifically instructed otherwise by your doctor or our staff at Cadabams Diagnostics.
- Wear Comfortable, Metal-Free Clothing: It's best to wear loose, comfortable clothing without any metal snaps, zippers, buttons, or metallic threads. You may be asked to change into a hospital gown to ensure there is no metal interference with the MRI scanner.
- Remove All Metallic Objects: Before entering the MRI scan room, you will need to remove all metallic items, including:
- Jewelry (necklaces, earrings, rings, bracelets, watches)
- Hearing aids
- Removable dental work (dentures with metal components)
- Eyeglasses
- Hairpins, barrettes, or other metallic hair accessories
- Body piercings (if they can be removed)
- Coins, keys, credit cards (the magnet can erase them)
- Pens Note: Lockers are usually provided at Cadabams Diagnostics for your personal belongings.
Metal Implants and Devices
- Inform Staff About Any Metal Implants or Devices: This is extremely important for your safety. You must inform the MRI technologist at Cadabams Diagnostics if you have any of the following:
- Cardiac pacemaker or implantable defibrillator (ICD)
- Cochlear implants
- Aneurysm clips (especially older types in the brain)
- Neurostimulators
- Drug infusion pumps
- Metal implants from previous surgeries (e.g., joint replacements, plates, screws, rods)
- Stents or vena cava filters
- History of metal fragments in your eyes (e.g., from metalwork)
- Shrapnel or bullet wounds
- Tattoos or permanent makeup (some older inks contain metallic particles, though this is rare) Our staff will review this information with you using a detailed safety questionnaire. Most modern orthopedic implants (like those used in shoulder replacements) are MRI-compatible, but it's crucial to declare them.
Claustrophobia or Anxiety
- Discuss Claustrophobia or Anxiety: If you are prone to claustrophobia or feel anxious about being in an enclosed space, please let our booking staff at Cadabams Diagnostics or your doctor know beforehand. We can discuss options to make you more comfortable, which might include listening to music through headphones, using an eye mask, or, in some cases, your doctor might prescribe a mild sedative to take before the scan.
- Arrange for a Driver if Sedated: If you do receive a sedative, you will not be able to drive yourself home and will need to arrange for someone to accompany you and drive you.
Pre-requisites
Doctor’s Referral
You will need a referral or prescription from your doctor (e.g., general practitioner, orthopedic specialist, rheumatologist) outlining the clinical reason for the scan. This helps the radiologist focus the examination and provide the most relevant information.
Safety Screening Form
Upon arrival at Cadabams Diagnostics, or sometimes beforehand, you will be asked to complete a comprehensive MRI safety questionnaire. This form asks about any metallic implants, previous surgeries, or conditions that might pose a risk during an MRI. Answering these questions accurately and thoroughly is crucial for your safety. Our technologists will review this form with you.
Medical History
It's helpful to inform the technologist or provide documentation regarding:
- The specific shoulder problem you are experiencing.
- Any previous injuries to the shoulder.
- Previous shoulder imaging studies (e.g., X-rays, ultrasounds, previous MRIs). If you have these reports or images, bringing them can be beneficial, although Cadabams Diagnostics may also be able to access them electronically if performed at affiliated facilities.
- Any relevant medical conditions (e.g., kidney disease, though less critical for non-contrast studies, it's good general knowledge).
Understanding the Procedure
While not a formal pre-requisite, having a basic understanding of what an MRI Shoulder Without Contrast entails, often gained from information like this page or discussion with your doctor, can help you feel more prepared and at ease.
Best Time to Take the MRI Shoulder Without Contrast
Scheduling Considerations
There is generally no "best" or "worst" physiological time of day to undergo an MRI Shoulder Without Contrast. The quality of the images is not typically affected by the time the scan is performed.
Availability and Urgency
The scheduling of your MRI will primarily depend on the availability of appointments at Cadabams Diagnostics and the clinical urgency determined by your referring doctor. If your condition is acute or requires prompt diagnosis, your doctor may request an earlier appointment.
No Time-of-Day Benefits
Unlike some blood tests that require fasting or specific timing, an MRI Shoulder Without Contrast does not have such requirements. Your body's natural state in the morning versus the afternoon will not impact the clarity of the shoulder images.
Personal Convenience
You can choose a time slot that is most convenient for your personal schedule, considering factors like work, family commitments, and transportation.
When Not to Delay
If your doctor has recommended the scan due to significant pain, injury, or suspicion of a serious condition, it's advisable to have the MRI Shoulder Without Contrast done as soon as reasonably possible to facilitate timely diagnosis and treatment.
Eligibility
Generally Eligible
Most people can safely undergo an MRI Shoulder Without Contrast.
Contraindications
These are critical safety concerns due to the powerful magnetic field:
- Incompatible Cardiac Pacemakers or Implantable Cardioverter Defibrillators (ICDs): Many modern pacemakers/ICDs are "MRI conditional," meaning they can be safely scanned under specific protocols. However, older or non-conditional devices are a contraindication. This will be carefully assessed at Cadabams Diagnostics.
- Certain Ferromagnetic Aneurysm Clips: Older types of clips used to treat brain aneurysms can be affected by the magnet. Newer clips are often MRI-safe, but verification is essential.
- Some Cochlear Implants: Certain cochlear (inner ear) implants are not MRI-safe.
- Certain Neurostimulators or Drug Infusion Pumps: Some implanted electronic devices may be incompatible.
- Metallic Foreign Bodies in Critical Locations: Such as metal fragments in the eye (which could move and cause damage). If there's a suspicion, an X-ray may be done first to check.
Relative Contraindications
These are situations where MRI may be done with caution, or alternatives considered:
- Severe Claustrophobia: While not an absolute contraindication, severe anxiety in enclosed spaces can make it difficult to complete the scan. Cadabams Diagnostics offers support, and options like open MRI (if available and suitable for shoulder imaging) or sedation prescribed by your doctor can be discussed.
- Pregnancy: MRI is generally avoided during the first trimester of pregnancy unless absolutely essential and the benefits significantly outweigh any potential (though not clearly established) risks. For an MRI Shoulder Without Contrast, the risk is considered very low, but it's always best to inform staff if you are or might be pregnant. Your doctor and the radiologist at Cadabams Diagnostics will discuss the best course of action.
- Inability to Lie Still: Patients who cannot remain still for the duration of the scan (typically 20-45 minutes) due to pain, tremors, or other conditions may not be good candidates, as movement degrades image quality.
- Significant Obesity: While Cadabams Diagnostics strives to accommodate all patients, very large individuals might exceed the weight or bore size limitations of a particular MRI machine.
Compatible Implants
Many individuals with metallic implants, such as joint replacements (including shoulder replacements), screws, plates, and rods, CAN safely have an MRI Shoulder Without Contrast. Most modern orthopedic implants are made of non-ferromagnetic materials like titanium or stainless steel alloys that are MRI-compatible. However, it's crucial to declare all implants during the screening process at Cadabams Diagnostics so their compatibility can be verified.
Procedure for Taking an MRI Shoulder Without Contrast
Step-by-Step Overview
- Arrival and Check-in: Arrive at Cadabams Diagnostics a little before your scheduled appointment to complete any remaining paperwork and the MRI safety checklist.
- Final Screening and Changing: A technologist will review your safety questionnaire and answer any questions you have about the shoulder mri no contrast procedure. You will be asked to remove any metallic items. You may be asked to change into a hospital gown to ensure no metal is present on your clothing.
- Positioning on the MRI Table: You will be asked to lie down on a padded, motorized table that slides into the MRI machine. For an MRI Shoulder Without Contrast, you will likely lie on your back. The technologist will help position you correctly.
- Shoulder Coil Placement: A special piece of equipment called a "surface coil" may be placed around your affected shoulder or positioned close to it. This coil acts like an antenna to help receive the radio signals from your body, improving the quality of the images. It is not painful and simply rests on or around your shoulder.
- Moving into the Scanner: Once you are comfortably positioned and the coil is in place, the table will slowly slide into the center of the MRI machine. The machine is a large, cylindrical tube that is open at both ends. Some newer machines at Cadabams Diagnostics may have a wider bore (opening) to reduce feelings of confinement.
- Scanner Noise and Communication: During the scan, the MRI machine will make loud, repetitive knocking, thumping, or buzzing sounds. This is normal and is the sound of the magnetic coils working. You will be provided with earplugs or specialized headphones to reduce the noise. The technologist will be in an adjacent control room but will be able to see you through a window and communicate with you via an intercom system. You will usually be given a call bell or squeeze ball to alert the technologist if you need assistance.
- Importance of Remaining Still: It is crucial to remain as still as possible during the entire shoulder mri no contrast procedure. Even small movements can blur the images, making them less useful for diagnosis and potentially requiring parts of the scan to be repeated. Try to relax and breathe normally.
- Scanning Process: The technologist will operate the MRI scanner from the control room. The scanning process involves several sequences, each lasting a few minutes. You will hear different patterns of noise for each sequence. The technologist may give you brief instructions or updates over the intercom between sequences.
- Scan Duration: The actual imaging part of an MRI Shoulder Without Contrast typically takes between 20 to 45 minutes, depending on the number of sequences required. The entire appointment time, including preparation, may be longer.
- Completion of the Scan: Once all the necessary images have been acquired, the table will slide out of the scanner. The technologist will assist you off the table.
- After the Scan: You can usually resume your normal activities immediately after an MRI Shoulder Without Contrast, as there are no lingering side effects from the scan itself. If you received a sedative, you would need to follow the specific post-sedation instructions provided (e.g., no driving).
Caution Before Taking the Test
Important Precautions
- Pregnancy: It is absolutely crucial to inform the staff at Cadabams Diagnostics if you are pregnant or if there is any possibility that you might be pregnant. While MRI is generally considered safe after the first trimester and does not use ionizing radiation, each case is evaluated individually, especially for non-emergency scans. For an MRI Shoulder Without Contrast, the risk is low, but disclosure is essential.
- Re-confirm All Metallic Implants, Devices, or Foreign Bodies: Even if you've mentioned them before, re-confirm any metal inside or on your body with the MRI technologist before entering the scan room. This includes pacemakers, aneurysm clips, cochlear implants, neurostimulators, surgical staples, metal plates, screws, artificial joints, shrapnel, or any history of working with metal where fragments could have entered your eyes. Accuracy here is vital for your safety during the MRI Shoulder Without Contrast.
- Mention Any History of Kidney Problems: Although contrast dye is not used in an MRI Shoulder Without Contrast (which is the primary concern for patients with kidney issues in MRI), it is still good practice to inform the medical team about any significant kidney disease as part of your overall medical history.
- Inform Staff if You Have Severe Anxiety or Claustrophobia: If you have a known history of severe claustrophobia or anxiety related to medical procedures or enclosed spaces, please discuss this with the Cadabams Diagnostics booking staff and the technologist well in advance. There may be strategies to help you manage this, or your doctor might prescribe medication.
- Difficulty Lying Flat or Still: If you have severe pain or a medical condition that makes it difficult for you to lie flat on your back or remain still for an extended period (20-45 minutes), please inform the staff. This can affect the ability to obtain clear images.
- Recent Tattoos or Permanent Makeup: While most modern tattoo inks are safe, some older inks, particularly red or dark colors, might contain metallic particles that could heat up during an MRI, causing skin irritation or, rarely, burns. Inform the technologist if you have large or dark tattoos in the area being scanned (though for a shoulder MRI, this is less common unless the tattoo extends onto the shoulder/upper torso).
- Medication Patches: Some medication patches contain metallic foil (e.g., nicotine patches, pain relief patches). These must be removed before the scan as they can heat up and cause burns. Discuss this with the technologist at Cadabams Diagnostics.
Test Results
Results and Interpretations
Finding / Observation | Description (What Radiologists Look For) | General Interpretation / Significance |
---|---|---|
Rotator Cuff Tendons | Evaluate supraspinatus, infraspinatus, subscapularis, and teres minor for integrity. Assess for partial/full-thickness tears, tendinosis, muscle atrophy, retraction, and fatty infiltration. | Rotator cuff pathology is a leading cause of shoulder pain. Tears may impair function; tendinosis reflects chronic overuse |
Glenoid Labrum | Assess labral contour, attachment to the glenoid, signal abnormality, or tears (e.g., SLAP, Bankart). Look for labral cysts, fraying, or detachment. | Labral damage may cause shoulder instability, pain, and mechanical symptoms like clicking or catching. |
Glenohumeral Joint & Articular Cartilage | Examine cartilage thickness, surface irregularity, subchondral bone marrow signal, joint space width, and loose bodies or osteophytes. | Detects osteoarthritis, chondral injury, or inflammatory changes within the joint that can limit range of motion or cause pain. |
Bursae (e.g., Subacromial-Subdeltoid Bursa) | Assess for fluid distention, bursal wall thickening, or associated impingement signs. | Bursitis is a common pain source and often coexists with rotator cuff pathology. Fluid may be reactive or inflammatory. |
Bones (Humerus, Scapula, Clavicle) | Evaluate bone marrow signal for edema, ischemia, or tumors. Check cortical integrity for fractures, and degenerative changes at AC joint. | May reveal stress fractures, contusions, cysts, or avascular necrosis. Also assesses for AC joint arthropathy. |
Biceps Tendon (Long Head) | Assess position in bicipital groove, signal intensity, partial tears, tendinosis, or tenosynovitis (fluid around tendon sheath). | Pathology here is common with rotator cuff disease and contributes to anterior shoulder pain. |
Acromioclavicular (AC) Joint | Examine for joint space narrowing, osteophytes, subchondral cysts, bone edema, and distal clavicle osteolysis. | Suggests degenerative arthropathy or impingement syndrome, and may correlate with pain during overhead activity. |
Soft Tissues (Muscles, Fat Planes) | Evaluate for muscle edema, atrophy, tears, or fatty infiltration. Assess surrounding fat planes for fluid collections or masses. | Reflects muscle injury or chronic denervation. Fatty atrophy often correlates with longstanding tendon tears. |
FAQs
Is an MRI Shoulder Without Contrast painful?
The MRI Shoulder Without Contrast scan itself is completely painless. You won't feel the magnetic fields or radio waves. Some people might experience mild discomfort from having to lie still in one position for the duration of the scan (20-45 minutes) or from the loud knocking sounds the machine makes (earplugs or headphones are provided to minimize this). If your shoulder is already very painful, the positioning might cause some temporary discomfort, which you should communicate to the technologist.
How long does the actual MRI Shoulder Without Contrast scan last?
The imaging part of the MRI Shoulder Without Contrast – the time you are actually inside the scanner and images are being acquired – typically lasts between 20 to 45 minutes. Please allow for additional time for pre-scan preparation, safety checks, and positioning, so your total appointment time at Cadabams Diagnostics might be around 60-90 minutes.
When will I receive the results of my MRI?
After your scan at Cadabams Diagnostics, a specialized radiologist will carefully review your MRI Shoulder Without Contrast images and prepare a detailed report. This report is usually sent to your referring doctor within [Cadabams Diagnostics to specify standard timeframe, e.g., 24-48 business hours, or "by the next business day"]. Your doctor will then schedule a follow-up appointment with you to discuss the results and their implications for your health.
