(Ultrasound, stereotactic or MRI-guided)
Ultrasound-guided, stereotactic and MRI-guided biopsies (also referred to as minimally invasive needle core biopsy) are performed by our Breast Care staff. With this procedure, the skin is cleansed and numbed with topical anesthetic. A small (1/4 inch) skin incision is made. A special biopsy needle is used to remove thin cores of tissue which are sent to a pathologist for analysis. At the end of the procedure, a small dressing is placed over the skin incision (no stitches are required). No sedation is needed for the procedure and the patient is allowed to drive upon leaving the facility.
The choice of ultrasound, stereotactic mammotome imaging or MR depends on what the abnormality looks like and which technique your radiologist deems most appropriate.
