MRI Guided Breast Biopsies

What is MR- guided breast biopsy?
Magnetic resonance- or MR-guided breast biopsy uses a powerful magnetic field, radio waves and a computer to help locate a breast lump or abnormality and guide a needle to remove a tissue sample for examination under a microscope. It does not use ionizing radiation and leaves little to no scarring.

What are some common uses of the procedure?
An MRI-guided breast biopsy is most helpful when MR imaging shows a breast abnormality such as:

– a suspicious mass not identified by other imaging techniques
– an area of distortion
– an area of abnormal tissue change
