X-ray Associates of NM was the first to offer this minimally invasive biopsy technique. MRI biopsy is performed in situations when an abnormal finding is detected on the MRI study but not convincingly seen on mammography or ultrasound.
The patient cannot have risk factors precluding MRI such as pacemaker or certain body devices. All patients are screened prior to MRI for risk factors. Potential risks of the biopsy procedure include bleeding and infection. This is explained in detail to the patient and consent obtained.
The patient is placed prone (on stomach) in the MRI machine with the affected breast lightly compressed. Generally, Gadolinium dye is then injected to confirm the abnormal site and its exact location. Following local numbing medicine and a small skin incision (about ¼ inches long), the biopsy needle is placed and samples removed through the needle. A clip is placed to mark the biopsy site.
The patient must refrain from strenuous activity for 24 hours.
MRI Guided Breast Biopsy is available at Breast Health and Imaging Center and X-Ray Associates at Santa Fe.
