MR-guided biopsy is a relatively new technique which involves using the MRI scanner to localized areas that are abnormal in the breast that may not be visible either by mammography or ultrasound. When these areas are localized then special devices and localizers then allow a needle to be placed into the vicinity of the area of abnormality. The patient is taken out of the scanner and through that guiding needle several biopsies are obtained.
