What is this test?

Magnetic resonance imaging of the spleen without contrast is an imaging test that creates detailed pictures of the spleen using a strong magnetic field and radio waves. Intravenous contrast material is not used.

Why might I need this test?

A healthcare professional may order this test to evaluate an enlarged spleen, investigate an area found on another scan, or assess spleen-related symptoms. It may also help characterize the appearance of spleen lesions or blood vessels.

How is the test performed?

You will lie on a movable table inside an MRI scanner. The scanner makes loud knocking and clicking sounds while taking images. You may be asked to hold very still or follow breathing instructions.

How do I prepare for the test?

Tell the imaging team if you have a pacemaker, other implanted medical device, metal in your body, or a possibility of pregnancy. Follow the facility's instructions about eating, drinking, medications, and removing personal items before the scan.

Frequently asked questions

Does this MRI use contrast material?
No. This version is performed without intravenous contrast, although other imaging from the same examination may be reviewed.
Is an MRI of the spleen painful?
The MRI itself is generally painless. The scanner can be noisy, and lying still inside the narrow scanner may feel uncomfortable for some people.
How long does the test take?
The time varies by facility and examination details. The imaging technologist can provide a more specific estimate before the test begins.
