What is this test?

This is an MRI scan of the axillary, or underarm, region. Intravenous contrast material is given through a vein to help produce clearer images of lymph nodes, blood vessels, and other nearby tissues.

Why might I need this test?

A clinician may order this scan to investigate enlarged underarm lymph nodes, a lump or mass, inflammation, infection, or the spread of a nearby condition. It may also be used to examine blood vessels and other structures in the axillary area.

How is the test performed?

You will lie on a padded table that moves into the MRI scanner. The scanner creates detailed images using magnetic fields and radio waves, and the injected contrast helps highlight certain tissues. The procedure may last from about 30 to 60 minutes, depending on the area being examined.

How do I prepare for the test?

Follow the imaging center's instructions and tell the staff about any metal implants, medication patches, pregnancy, kidney disease, or prior reaction to MRI contrast. You may need to change into a gown and remove jewelry, watches, hairpins, and other metal objects. Fasting may be requested only if the center specifically instructs you to do so.

Frequently asked questions

Is this an x-ray?
No. This test uses MRI, which creates images with magnetic fields and radio waves rather than radiation.
Why is contrast given through a vein?
The contrast can make lymph nodes, blood vessels, and other tissues easier to distinguish from surrounding structures.
What if I am allergic to contrast or have kidney disease?
Tell the imaging staff before the scan. They can review your history, discuss your risks, and determine whether contrast should be used or adjusted.
