CT SCAN OF HIP JOINTS

A hip joints CT scan is an imaging test that uses X rays and computers to detail cross-sectional images of the hip's joints and surrounding tissues. It assists physicians in diagnosing and treating complex degenerative issues with the precision imaging technology, fractures and tumour problems in the hips. Prior to the test, there is a preparation phase which includes taking off all metallic ornaments like jewellery, spectacles or clothing with metal hooks and changing into a hospital gown. You may need to not eat anything for a few hours before the test or skip some specific medicine. 

What is a CT scan of Hip Joints? 

During the exam, a patient lies on a table and goes inside the mouth of a large, doughnut shaped machine called a CT scanner. An X-ray machine attached to a computer rotates and slides from side to side while taking images of the patient's body. A CT scan of hip joints is a procedure done for detailed imaging of all the structures in the hips and the hip joints body including bones, cartilage and soft tissues. 

Types of CT scan of Hip Joints 

• Non-Contrast CT scan of Hip Joints- Assessing the bones and soft contours of the hip joint is the purpose of this type of scan.  
• Contrast-Enhanced CT scan of Hip Joints- The conjunct for the hip joint and the blood vessels as well as the surrounding soft tissues are evaluated through this type of scan.  
• CT Arthrogram of Hip Joints - This type of the scan utilizes the contrast injection into the hip joint to assess the joint cavity and its adjacent structures.  

List of Parameters Considered During the CT scan of Hip Joints

The following are the considerations while carrying out the scan: 

• Narrowing joint space: The distance where the two bones of the hip joint are located. 
• Bone mass: The mass of the bones which are surrounding the hip joint. 
• Tissue concern: Infringing changes in soft tissue structures like tendons and ligaments. 
• Cartilage thickness: The volume of the cartilage wherever it is found in the hip joint. 

Reasons for Taking a CT scan of Hip Joints

• Determine diseases like osteoarthritis, fractures, and tumours. 
• Monitor treatment: Track the progress of treatment regarding the patient's hip joint pathology. 
• Guide injections: Direct the injection of steroids or other drugs into the hip joint. 

When and Who Needs to Take a CT scan of Hip Joints? 

A hip joint CT scan may be advised for the following reasons: 

• Pain and/or stiffness in the hip region 
• Decreased range of motion in the hip joint 
• Recent injury or trauma to the hip region 
• Signs of osteoarthritis, which include pain and stiffness in the joints 
• Results that are outside the range of normal from a physical exam or X-ray 
• Patients who are deemed medically fit to undergo hip replacement surgery 

The test is recommended for most adults and older children who can adequately cooperate with the procedure.  

Benefits of Taking the Test

• Accurate diagnosis: Obtains precise images of the hip and surrounding structures. 
• Non-invasive: No surgical or instrument penetration is involved. 
• Pain relief: Injections of pain-relief drugs can be facilitated. 

Illnesses Diagnosed with CT scan of Hip Joints

• Osteoarthritis 
• Fractures 
• Tumours 
• Inflammatory arthritis 
• Hip impingement 

Preparing for CT scan of Hip Joints

• Remove any metal accessories including rings, glasses and clothing with metallic clasps. 
• Don a patient’s gown. 
• Refrain from eating a few hours prior to the test and avoid certain medications, if directed by your physician. 

Pre-requisites 

• Remove safety glasses. 
• Explain any implanted devices, like a cardiac pacemaker, to the doctor. 
• Explore any allergies to contrast materials with the doctor. 

Best Time to Take the CT scan of Hip Joints 

The procedure is not time-locked; however, it is best scheduled closer to dates along follow-up visits. 

Eligibility 

This examination is often suggested for both adults and children who can remain calm during the scanning procedure. Certain medical issues might require additional tests or safety measures before having a CT scan of the hip joints done, like having kidney disease. 

Procedure For Taking CT scans of Hip Joints 

1. You'll receive instructions to lie down on a bed that moves into the CT scanner. 
2. You're going to be prompted to stay still and breathe in short intervals during the scanning process. 
3. The total scanning time is usually between 15 minutes and 30 minutes. 
4. There may be a need to administer the contrast agent through a peripheral IV catheter to better visualize the soft tissues and blood vessels. 

Caution Before Taking the Test 

• Report any allergies to contrast agents to your physician. 
• Report any surgically implanted devices like pacemakers to your physician. 
• Adhere to instructions given by your doctor or the CT technologist concerning medications, meals, and water before the examination.
