What is this test?

Magnetic resonance imaging, or MRI, creates detailed pictures of the lower leg using magnetic fields and radio waves. This test is performed without gadolinium-based contrast dye injected into a vein.

Why might I need this test?

A lower-leg MRI may be ordered to evaluate persistent pain, swelling, trauma, or suspected problems involving bones, muscles, tendons, ligaments, nerves, or other soft tissues. It can also help characterize a lump or other abnormal finding seen on another imaging test.

How is the test performed?

You will lie on a padded table while the MRI machine creates images from several angles. The scan may take 30 to 60 minutes and can be noisy. You may be asked to remain still or hold your breath briefly.

How do I prepare for the test?

Tell the imaging staff about any metal in your body, implanted medical devices, pregnancy, or allergy to contrast dye. Remove jewelry, watches, hairpins, and other metal items before the scan. Because contrast is not used, fasting is usually unnecessary, but follow any instructions from the imaging center.

Frequently asked questions

Does this MRI use contrast dye?
No. “Without contrast” means gadolinium-based contrast dye is not injected for the scan. Some facilities may use a different preparation, so confirm the instructions before your appointment.
Is a lower-leg MRI painful?
The scan itself is generally painless. Some people feel confined or uncomfortable inside the scanner, but the technologist can usually provide guidance, and breaks may be possible for longer scans.
Why might both lower legs be scanned?
Comparing the painful or affected leg with the other side can help identify subtle changes and distinguish normal anatomy from abnormalities. The reason and scan area are determined by your ordering clinician and the imaging center.
