What is this test?

This is an imaging evaluation of the breast that may include magnetic resonance imaging (MRI), ultrasound, or both. A contrast material may be given through a vein to help highlight areas of concern.

Why might I need this test?

It may be used to investigate a lump, nipple change, or other breast symptom, particularly when mammography or ultrasound results are unclear. It may also be used for people with a high risk of breast cancer or a known breast cancer to help assess the extent of disease.

How is the test performed?

For MRI, you lie in a scanner while images are taken, usually with one or more contrast injections. For ultrasound, a technician moves a probe over the breast using gel; contrast-enhanced ultrasound may also involve an injection.

How do I prepare for the test?

Follow the imaging center's instructions and tell the staff about contrast allergies, kidney disease, pregnancy, breast implants, or implanted medical devices. Metal items and jewelry must be removed for MRI, and you may be asked to change into a gown.

Frequently asked questions

Is this test the same as a mammogram?
No. A mammogram uses low-dose X-rays, while breast MRI uses a magnetic field and radio waves. Ultrasound uses sound waves and is often performed as an additional test.
Do I need to have contrast for this test?
It depends on the protocol and the specific examination ordered. The imaging center will explain whether an intravenous contrast agent will be used and how it will be administered.
Will a breast MRI show that I have cancer?
Not by itself. MRI can identify suspicious areas, but imaging features and other clinical information must be reviewed, and a biopsy is usually needed to confirm cancer.
