Breast Biopsy

Ultrasound-Guided Procedures

Ultrasound-guided breast biopsy is a procedure that uses ultrasound to enable the radiologist to obtain small samples of breast tissue. Ultrasound images are obtained of a localized area for biopsy. A local anesthetic is then used to anesthetize the area for biopsy.

Ultrasound is used as a guide for the radiologist to place the needle in the breast. After proper placement of the needle, several samples of tissue are then obtained. These are sent to the pathologist for microscopic examination.

• Solid Breast Masses may undergo biopsy (tissue sampling) using Ultrasound localization. Diagnosis may be made using little more than a needle and Band-Aid.
• Cysts may be aspirated (drained) and fluid analyzed.

Stereotactic Breast Biopsy Techniques
Imaging techniques play an important role in helping doctors perform breast biopsies, especially of abnormal areas that cannot be felt but can be seen on a mammogram or with ultrasound. One type of needle biopsy, the stereotactic-guided biopsy, involves the precise location of the abnormal area in three dimensions using digital mammography. Stereotactic refers to the use of a computer and scanning devices to create three-dimensional images. Following local anesthesia, a needle is then inserted into the breast and tissue samples are obtained. These are sent to the pathologist for microscopic examination.
