CT LEG

CT leg scans are pictures of legs that are taken with an X-ray scanning device and a computer in combination. This method enables physicians to view internal structures (such as tissues, organs, and blood vessels) inside the legs more clearly than traditional X-rays. A CT leg scan is ordered when other tests do not give a clear treatment or diagnosis. As a CT scan is non-invasive, it is frequently done for diagnosing a variety of conditions like injuries, pain, infections, and disease of the legs. If you have any metal objects, you will have to take them off too prior to the CT leg scan. 

What is a CT Leg Scan? 

A CT leg scan is done using a wide donut-shaped machine that makes use of X-ray technology to take pictures of the legs. The X-ray machine captures darker contrasting images of the legs which are then turned into images with the help of a computer. Compared to other medical equipment, CT scans give a clearer and more detailed image of the person. As the leg gets the most activity, it is very difficult for doctors to identify fractures and other forms of injuries in the legs using other forms of X-rays. 

Types of CT Leg Scans 

Some of the more common types of CT leg scans include: 

• Non-contrast CT leg scan: This variation is the most popular and it utilizes no contrast dye whatsoever. 
• Contrast CT leg scan: This type is performed with the use of contrast dye for image clarification. It is commonly employed when diagnosing vascular disorders, tumours, or any vascular related problems. 
• Spiral CT leg Scan: This captures the images of the legs in a spiral motion. It is also performed on patients with metal implants or pacemakers. 

List of Parameters Considered During the CT Leg Scan

The medical team considers these factors during the scan: 

• Alignment of the legs: How the limbs are placed at the time of the scan. 
• The bones’ density: The level of density of the bones in the examined limb. 
• Remainder of soft tissues: Level of condition of muscles, tendons and ligaments of the limb. 
• Vascular Structure: Status of the blood vessels of the limb. 

Reasons for Taking a CT Leg Scan

A CT scan of the legs may be indicated in a variety of conditions such as: 

• Fractures or dislocated bones 
• Thrombophlebitis of the lower limb veins (DVT) 
• Infection of bone tissue (Osteomyelitis) 
• Infection of cellulitis (cellular tissues of skin and subcutis) 
• Vascular diseases like atherosclerosis of peripheral vessels (PAD) 

When and Who Needs to Take a CT Leg Scan? 

Patients most suited to receiving a CT leg scan are those:  

• Having cutting injuries to the legs like fractures or dislocations  
• Positive with symptoms for Deep vein thrombosis (DVT). For example, swelling and pain, or warmth in the legs.  
• Having leg pain or weakness which is progressive.  
• Having suspicious osteomyelitis (bone infection) or cellulitis infection skin.  
• Suffering from vascular conditions like peripheral artery disease (PAD). 

Benefits of Taking the Test

CT scan has many advantages and some of them includes -  

• High level of precision in diagnosis – The conditions are diagnosed accurately because the scan shows the body part in detail.  
• Not invasive - The examination is simple in term of not needing to cut the skin or insert any devices.  
• Speedy and painless - The device is set to scan for only a few minutes and there is no pain involved. 

Illnesses Diagnosed with CT Leg Scan

A CT leg scan can identify numerous conditions, for example:  

• Fractures or Dislocated Bones  
• Thrombosis of Deep Veins (DVT)  
• Bone infections (Osteomyelitis)  
• Cutaneous and subcutaneous tissue infection (Cellulitis)  
• Vascular diseases such as peripheral artery disease (PAD) 

Preparing for the CT Leg Scan

To prepare for the scan, patients should:  

• Dressing in loose-fitting and comfortable clothes  
• Taking off all metallic items  
• Fasting for several hours prior to the scan 

Pre-requisites 

A patient does not need to meet any specific requirements before undergoing a CT leg scan. However, the patient is encouraged to notify their doctor of any: 

• Metal devices or cardiac pacemakers  
• Disease of the kidney  
• Contrasting dye allergy 

Best Time to Take the CT Leg Scan 

Although the scan can be done at any time, it is more practical to organize it so that it can take place in the morning for any follow up tests or appointments that may need to be made. 

Eligibility  

A patient from any background can undergo a CT leg scan, however, it is preferred for those who are: 

• Having complications with leg injuries or diseases. 
• Suspected to have vascular health issues. 
• Struggling with unobstructed leg discomfort or weakness and need a proper diagnosis. 

Procedure for Taking a CT Leg Scan 

CT leg scan is believed to be one of the easiest to preform leg region scans. It is performed in the following steps:  

1. Patient preparation: The patient undresses and puts on a hospital gown. All metal items are relinquished.  
2. Scan preparation: The technician prepares the CT scanner and puts the patient on the table.  
3. Scan: The procedure takes only a couple of minutes and while it's taking place, the patient needs to relax and do in no circumstances move.  
4. Image analysis: The images are then assessed by the technician who also composes a report to the diagnosing doctor. 

Caution Before Taking the Test 

Patients ought to tell the doctor's office about any:  

• Metal implants or pacemaker.  
• Diabetes concerning the kidneys.  
• Allergic reactions concerning the contrast dye.  
• Being pregnant or nursing.
