MRI Guided Biopsy

Magnetic resonance imaging (MRI)-guided breast biopsy uses a strong magnetic field, radio waves, and a computer to help a breast surgeon locate a breast lump or abnormality. The doctor then guides a needle to remove a tissue sample for examination. The contrast between normal tissues and abnormal tissues is frequently clearer with an MRI than with an X-ray, ultrasound, or computed tomography (CT) scan.

MRI-guided breast biopsies are typically performed in an outpatient basis using a local anesthetic to numb the skin and the breast prior to the removal of the sample tissue.

While MRI-guided breast biopsies can sometimes detect a suspicious mass or distortion not identified by other imaging techniques, mammography or ultrasound is preferred.
