What is this test?
Magnetic resonance imaging, or MRI, uses magnetic fields and radio waves to create detailed pictures. Intravenous contrast is a dye injected through a vein to help certain tissues and abnormalities appear more clearly.
Why might I need this test?
A left axillary MRI may be recommended to evaluate a lump or swelling, enlarged lymph nodes, infection, inflammation, injury, or a suspected tumor. It can also show how a finding relates to nearby muscles, skin, blood vessels, and nerves.
How is the test performed?
You will lie on a table that moves into the MRI scanner. If contrast is being used, a clinician will inject it into a vein, usually in an arm, and the scanner will take several images of the left armpit.
How do I prepare for the test?
Follow the facility's instructions and tell the care team about any metal implants, medication patches, severe kidney disease, prior contrast reactions, or possible pregnancy. You may need to avoid eating or drinking for a period if sedation is planned.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
MRI findings may indicate a benign cyst or scar, inflammation, infection, enlarged lymph nodes, or a mass that requires further evaluation. The radiologist's interpretation should be considered together with your symptoms, examination, and any prior imaging. A suspicious finding may lead to additional imaging or a tissue sample, but MRI alone does not establish whether a mass is cancerous.
