What is this test?

A CT scan uses X-rays and computer technology to create detailed images of the adrenal glands, which sit above each kidney. This version is performed without injected contrast dye.

Why might I need this test?

Your clinician may order this test to evaluate an adrenal nodule, mass, enlargement, or suspected adrenal disorder. It may also be used to assess the adrenal glands when symptoms or other test findings suggest a problem.

How is the test performed?

You will lie on a table that moves through a CT scanner while X-ray images are taken. The scan is painless and usually takes only a few minutes, although you may be asked to hold your breath briefly.

How do I prepare for the test?

Special preparation is often not required for a CT scan without contrast. Follow your clinician's instructions, and tell the imaging facility if you are pregnant, may be pregnant, or have any allergies.

Frequently asked questions

Does this CT scan use contrast dye?
No. This test is performed without injected contrast dye. If another CT scan with contrast is needed, the imaging facility will provide separate instructions.
Is an adrenal CT scan painful?
The scan itself is generally painless. Some people may feel brief pressure or discomfort from the table, and they may be asked to hold their breath while images are taken.
Will the results diagnose an adrenal disorder?
Not by themselves. Imaging can identify structural abnormalities, while symptoms, hormone testing, and other clinical findings are often needed to determine the cause.
