What is a breast MRI (magnetic resonance imaging)?
A breast MRI is a type of imaging test that uses magnets, radio waves and computer software to create detailed images of the breast. It’s a diagnostic test for several reasons, from implant leakage to breast cancer screening.
Unlike a mammogram, a breast MRI does not use radiation. Instead, the combination of a magnetic field and a pulse of radiofrequency waves cause atoms in your body to send out signals that are detected by a computer and converted into images. You may also have a special dye, called contrast, to enhance the images. If you need a breast MRI, your care team will guide you through each step so you know what to expect.
