A MRI guided breast biopsy is a type of core needle biopsy that acquires breast tissue without surgery. It is performed when the area of concern cannot be clearly shown through other imaging methods. The MRI imaging technique achieves several, cross-sectional images of your breast tissue and, with the help of a computer, generates three dimensional pictures to guide your doctor.
For this procedure you will lie face down on a padded examination table, with your breast positioned through a round opening in the table. The table is then elevated several feet so that your doctor is seated below. (The procedure can also be performed while you sit in a chair, if you are unable to lie on your abdomen.)
Next, the area on your breast will be sterilized with rubbing alcohol or iodine. Typically, an injection of local anesthetic is given to numb the area where the needle will be inserted. Once the anesthetic has taken effect, your doctor will make an incision approximately one quarter inch long, and extract tissue samples from the lump. The entire procedure lasts approximately one hour.
