When Is a CT Leg Plain Recommended?
Doctors may advise a CT scan of the leg in the following cases:
- Persistent leg pain or swelling after trauma
- Detection of small fractures not clear on X-rays
- Review of bone alignment before or after orthopedic surgery
- Assessment of bone healing after fixation or implant placement
- Evaluation of bone cysts, tumors, or abnormal growths
- Preoperative planning for joint replacement or reconstruction
How the CT Leg Scan Is Performed
During the procedure, you’ll be asked to lie down on the CT table while the affected leg is placed inside the scanner. The scanner rotates around the leg, capturing multiple cross-sectional images. These images are processed by computer software to build detailed 3D visuals of your leg bones and joints.
The scan usually takes 7–10 minutes. Since this is a plain (non-contrast) scan, no dye or contrast injection is used.
Preparation and Safety Tips
Before coming for your scan:
- Remove any metallic objects, belts, or jewelry around the leg area.
- Wear comfortable, loose-fitting clothes or a hospital gown.
- Pregnant women should inform the radiology team in advance.
- CT scans use a very low level of radiation and are considered safe for most patients.
Understanding Your CT Leg Scan Results
Once completed, the CT images are reviewed by a radiologist, who provides a detailed report to your doctor. These images help in identifying:
- Microfractures and bone cracks
- Infections or bone inflammation
- Joint surface abnormalities
- Surgical hardware position and healing progress
- Structural deformities or tumor formations
- The report guides orthopedic specialists in planning effective treatment, surgery, or rehabilitation strategies.
Why Choose a CT Leg Plain Scan
- Produces high-resolution bone imaging for accurate assessment
- Fast and non-invasive procedure with quick recovery
- Detects complex fractures missed on plain X-rays
- Essential for orthopedic surgery planning and postoperative monitoring
- No contrast required, making it ideal for patients prone to allergies
