What is this test?

This is an MRI scan of the nasopharynx, the area behind the nose and above the throat. Intravenous contrast is given through a vein to help highlight certain tissues, blood vessels, inflammation, or abnormal growths.

Why might I need this test?

A nasopharynx MRI with contrast may be used to evaluate persistent nose or ear symptoms, unexplained facial or neck symptoms, suspicious lymph nodes, or a mass found during another examination. It may also be used to plan or monitor treatment.

How is the test performed?

You lie on a moving table inside the MRI scanner, which uses strong magnetic fields and radio waves to create images. The care team may place an IV line, inject contrast, and ask you to remain still for several sequences.

How do I prepare for the test?

Follow the instructions provided by the imaging center. Tell the care team about contrast allergies, kidney disease, pregnancy, implanted devices, or any metal in your body. You may need to avoid eating or drinking beforehand, especially if sedation is planned.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

The scan may reveal inflammation, infection, enlarged lymph nodes, cysts, or abnormal tissue in the nasopharynx. Findings are interpreted together with your symptoms, examination, and other tests, so the radiologist's report should be reviewed with your clinician.

Short name

Frequently asked questions

Is the MRI with contrast painful?
The MRI itself is generally painless, although the scanner can be noisy and may feel confined. The IV injection may cause a brief cool or warm sensation, and some people feel flushed afterward.
Will I be exposed to radiation?
MRI does not use ionizing radiation. The contrast material used for this type of scan is not the same as the contrast used for CT scans.
How long does the test take?
The exact time varies by facility and the images needed. Contrast-enhanced MRI often takes longer than a routine MRI because additional images are acquired after the injection.
