Important information to know


Magnetic resonance imaging (MRI) Guided Breast Biopsy is an outpatient procedure. It is less invasive than surgical biopsy and only requires local anesthetic to numb the biopsy site. The radiologist will remove a tissue sample under MRI guidance to be analyzed to determine if the growth is benign or cancerous. You can return to most normal daily activities the same day.

MRI-Guided Breast Biopsy takes about 1.5 hours to complete. During your exam, the affected breast(s) are positioned in a cushioned area and lightly compressed. Under the guidance and supervision of a breast radiologist, MR imaging guides a needle to the correct location to remove breast tissue.
