What is this test?

A CT scan uses X-rays and a computer to create detailed images of the foot. This version is performed without iodinated intravenous contrast.

Why might I need this test?

It may be used to evaluate fractures, infections, foreign bodies, bone abnormalities, or persistent foot pain when standard X-rays do not provide enough information.

How is the test performed?

You will lie on a table while a CT scanner directs X-rays around your foot. The scan is painless and usually takes a short time, but you must remain still.

How do I prepare for the test?

Fasting is generally not required for a CT scan without contrast. Wear comfortable, loose clothing and tell the technologist about any metal objects, implants, pregnancy, or previous contrast reactions. Follow the imaging center's specific instructions.
