What is this test?
Computed tomography, or CT, uses X-rays to create detailed cross-sectional images of the right ankle. Contrast material may be used to make particular tissues, injuries, or abnormalities easier to see.
Why might I need this test?
A right ankle CT may be ordered to evaluate a suspected fracture that is not clearly visible on standard X-rays, or to assess complex bone or joint injuries. It may also help identify infection, inflammation, tumors, or other structural changes.
How is the test performed?
You will lie on a scanning table while an X-ray machine circles the ankle and creates images from different angles. If contrast is required, it may be given through a vein or into the ankle joint, depending on the specific procedure. The scan usually takes a relatively short time.
How do I prepare for the test?
Follow the preparation instructions provided by the imaging facility, especially if contrast will be used. Tell the care team about any prior contrast reaction, medication or iodine allergy, kidney disease, or possible pregnancy. Remove metal objects and loose items from the ankle area when instructed.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may indicate a fracture, joint injury, infection, inflammation, bone lesion, or another structural problem in the ankle. The images are interpreted by a radiologist, and the results should be considered together with your symptoms, physical examination, and other tests. The ordering clinician will explain whether any follow-up is needed.
