What is this test?

Magnetic resonance imaging, or MRI, creates detailed pictures of the lower leg using magnetic fields and radio waves. Intravenous contrast may be given through a vein to help certain tissues and abnormalities appear more clearly.

Why might I need this test?

A lower-leg MRI may be ordered to investigate persistent pain, swelling, an injury, suspected infection or inflammation, a mass, or problems involving bones, muscles, tendons, blood vessels, or nerves.

How is the test performed?

You will lie on a table that moves you into a large MRI scanner. If contrast is needed, it is usually injected into a vein before or during the scan, and the technologist may take several series of images.

How do I prepare for the test?

Follow the facility's instructions and tell the care team about pregnancy, kidney disease, prior contrast reactions, implanted medical devices, or metal in the body. You may be asked to remove loose items and change into a gown or clothing without metal.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Does the lower-leg MRI use radiation?
No. MRI uses magnetic fields and radio waves rather than ionizing radiation.
Is IV contrast always required for this test?
The order specifically includes IV contrast, but the care team will confirm the planned procedure and any necessary safety screening.
Will I need to stay still during the scan?
Yes. You should remain as still as possible while the images are taken, and the technologist may provide instructions or assistance if you feel uncomfortable.
