    Magnetic Resonance Imaging (MRI) of the Breast



    What Affects the Test

    Reasons you may not be able to have the test or why the results may not be helpful include:

    • Pregnancy. An MRI test usually is not done during pregnancy. If you are pregnant, an ultrasound test may be done instead.
    • Medical devices that have metal, such as a Reference pacemaker Opens New Window or an Reference ICD Opens New Window. These devices may not function properly or can cause problems during an MRI scan.
    • Other types of metal, such as surgical clips. If these will interfere with a breast MRI, the test will not be done.
    • Inability to remain still during the test.
    • Being very overweight. This may affect your ability to fit into the opening of some standard MRI machines.
