What is this test?

A left ankle CT with contrast is an X-ray-based imaging study that produces detailed pictures of the ankle. Contrast material may help improve the visibility of certain tissues and abnormalities.

Why might I need this test?

Your clinician may order this test to investigate a suspected fracture, tendon or ligament injury, arthritis, infection, or another problem that is not clearly visible on standard X-rays.

How is the test performed?

You will lie on a table while the CT scanner rotates around your ankle. If contrast is used, it is usually given through a vein, and the scan is completed quickly, although the total visit may take longer.

How do I prepare for the test?

Follow the facility's instructions and tell the imaging team about contrast allergies, kidney disease, pregnancy, or medications such as metformin. You may be asked not to eat or drink for a short period, depending on the contrast protocol.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

The scan may identify fractures, bone abnormalities, joint changes, tendon or ligament injuries, infection, or a foreign body. Results should be interpreted by a radiologist in the context of your symptoms and the physical examination.

Short name

Left ankle CT with contrast

Frequently asked questions

Is this a blood test?
No. It is a CT imaging study of the left ankle, although contrast material may be injected through a vein.
How long does the CT scan take?
The actual imaging is usually brief, but check-in, contrast administration, and preparation can make the full appointment take longer.
What should I do if I am allergic to contrast material?
Tell the imaging facility before the appointment. The team can determine whether contrast should still be used and how to monitor you safely.
