What is this test?
Breast MRI is an imaging test that uses strong magnetic fields and radio waves to create detailed pictures of the breasts. For this test, a gadolinium-based contrast material is given through a vein to help certain breast tissues appear more clearly.
Why might I need this test?
Breast MRI may be used to evaluate a lump, nipple discharge, or an area of concern found on mammography or ultrasound. It may also be used for people at higher risk of breast cancer, to look for cancer that is not visible on standard mammography, or to assess breast implants.
How is the test performed?
You will lie on a table inside the MRI scanner while images are taken. An IV line will be used to inject the contrast, and the scan usually includes images before and after the contrast is given. The procedure generally takes 30 to 60 minutes and is painless, although the scanner can feel confined and noisy.
How do I prepare for the test?
Tell the imaging team about all implants, metal medical devices, prior contrast reactions, kidney disease, and pregnancy or breastfeeding. Remove jewelry, hairpins, watches, and other items with metal. Follow the facility's instructions about medications and eating or drinking before the appointment.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal MRI findings can reflect a benign condition, such as a cyst or fibroadenoma, but some areas of enhancement or mass formation may be concerning for cancer. MRI results are interpreted by a radiologist and considered together with your medical history, examination, mammogram, ultrasound, and prior images. Additional imaging, follow-up, or a biopsy may be recommended.
