What is this test?

Magnetic resonance imaging, or MRI, creates detailed pictures of the lower leg using magnetic fields and radio waves. Intravenous contrast, usually gadolinium-based, may be given through a vein to improve the visibility of certain tissues, blood vessels, inflammation, or masses.

Why might I need this test?

A lower-leg MRI may be recommended to evaluate a suspected fracture, bone or joint problem, tendon or ligament injury, muscle damage, infection, inflammation, or a tumor. Your clinician will explain the specific reason for the examination.

How is the test performed?

You will lie on a table that moves into the MRI scanner. The scanner makes loud knocking, ringing, or clicking sounds, and you may be asked to remain still. If contrast is used, it is administered through an intravenous line before or during the scan.

How do I prepare for the test?

Follow the imaging center's instructions about medications, eating, and drinking. Tell the care team if you have metal implants, a pacemaker or other electronic device, kidney disease, a prior contrast reaction, or are pregnant or breastfeeding. Remove jewelry, hearing aids, and other items that may contain metal before the examination.

Frequently asked questions

Does this MRI use radiation?
No. MRI does not use ionizing radiation, although injected contrast can rarely cause an allergic-like reaction.
Will I feel the intravenous contrast?
The injection may feel like a brief sting or pressure. Significant reactions are uncommon, but tell the care team immediately if you develop severe symptoms such as trouble breathing, facial swelling, or dizziness.
Can I get this MRI if I have metal in my body?
Many medical implants are MRI-safe, but some are not or require special precautions. Provide the care team with details about every implant, device, and piece of metal before the test.
