MR Guided Breast Biopsy Procedure Information
Your doctor has requested an MRI-guided breast biopsy. The goal of a biopsy is to remove a small sample of tissue for testing in a laboratory. A biopsy can help diagnose abnormalities such as infection, inflammation or malignancy. During your biopsy, an imaging physician will use an MRI scanner to accurately guide a needle to the biopsy site. The needle will then be used to remove a tissue sample. At the S. Mark Taper Foundation Imaging Center a highly-trained medical team will oversee your procedure. This team will include an imaging physician and an imaging technologist.

During Your Exam
You will be asked to lie face down on the scanner table.
The table you are on will slide into the scanner. This process usually includes multiple scans, so you will likely slide into the scanner more than once. It is very important that you do not move.
The scanner is open at the back and the front, allowing you to see out. The technologist will always be able to see and hear you during your exam.
You will be asked to hold very still and at times to breath shallowly with no deep breaths that would change your position.
The exact location of the area of interest is identified and the area for incision is numbed.
The imaging physician will perform the biopsy and remove a tissue sample.
A small titanium marker clip will be placed to mark the area that was biopsied.
A pressure bandage and wrap will be applied after the procedure, as well as an ice pack.
This procedure usually takes approximately 60 to 90 minutes.

You will be moved to a room for observation by our nursing staff. You will need to remain in the room for approximately one hour, during which time, your vital signs will be monitored.
You may eat and drink as normal after leaving the center.
The pressure bandage can be removed after 16 hours. Please allow the Steri-strips to fall off on their own in 3 or 4 days.
Do not shower or bathe for 24 hours after your biopsy.
Do not take Aspirin or Ibuprofen for 48 hours after the biopsy.

You may experience some soreness and/or bruising, which can usually be alleviated with an over-the-counter pain reliever and by applying an ice pack to the biopsy site.
