What is this test?

This is an MRI scan of the parotid glands performed after receiving intravenous contrast. It creates detailed images that can show gland tissue, swelling, cysts, masses, and nearby structures.

Why might I need this test?

Your clinician may order this test to investigate a lump, swelling, pain, drainage, or an enlarged parotid gland. It may also help characterize a finding seen during an examination or another imaging study.

How is the test performed?

You will lie on a table while an MRI machine creates images of the head and neck. IV contrast is usually given through a vein in your arm before the scan, and the scan itself generally does not cause pain.

How do I prepare for the test?

Tell your clinician if you have kidney disease, prior contrast reactions, implanted medical devices, or might be pregnant. Follow the facility's instructions about medications, eating, drinking, and removing metal items before the appointment.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

An abnormal result may show a mass, cyst, inflammation, infection, duct obstruction, or a salivary stone. A benign-appearing or concerning mass may require comparison with prior studies or additional testing; the MRI images are interpreted by a radiologist and reviewed with your clinician.

Short name

Contrast-enhanced parotid gland MRI

Frequently asked questions

Is contrast-enhanced parotid gland MRI painful?
The scan itself is usually painless, although lying still in the MRI machine can feel uncomfortable. The IV needle may cause brief pain or bruising, and some people experience warmth, nausea, or a headache from the contrast.
Does the test use radiation?
No. MRI does not use ionizing radiation, although intravenous contrast may be used to improve the detail of the images.
How soon will I receive the results?
A radiologist will interpret the images and send a report to your ordering clinician. The timing of review and discussion varies by the healthcare organization and the urgency of the findings.
