Schematic representation of a vacuum-assisted biopsy probe. Mammotome is a Cincinnati, Ohio–based company who pioneered a vacuum-assisted breast biopsy (VAC) device that uses image guidance such as x-ray, ultrasound and/or MRI to perform breast biopsies. A biopsy using a Mammotome® device can be done on an outpatient basis with a local ...
One method is wire-guided (or wire-localized) excisional biopsy, where a wire is inserted into the breast and repeatedly imaged using breast ultrasound or mammography until the technician sees that the tip is located in the suspicious area. The suspicious area is then removed entirely in one block by the surgeon with the help of the wire.
Stereotactic biopsy, also known as stereotactic core biopsy, is a biopsy procedure that uses a computer and imaging performed in at least two planes to localize a target lesion (such as a tumor or microcalcifications in the breast) in three-dimensional space and guide the removal of tissue for examination by a pathologist under a microscope.

Ultrasound is also used surgically. Specifically, an ultrasound-guided needle biopsy allows providers to see the needle so it can be directed toward the lesion of concern while avoiding other critical structures such as blood vessels. [40] Ultrasound-guided biopsies have also been shown to decrease re-excision and mastectomy rates in breast cancer.
Similarly to the 3D ultrasound technique used for pregnant women, AWBU allows volumetric image data to be obtained from ultrasound sonography. With automated whole-breast ultrasound, the ultrasound transducer is guided over the breast in an automatic manner.
Ultrasound, also known as sonography, is commonly used for evaluating potential symptomatic breast lesions. Ultrasound can also be used to guide biopsy needles to particular regions of interest in the breast. It can also be used to help differentiate cysts from solid tumors based on the size, echo pattern, and vascularity of the mass. [52]
Breast ultrasound is also used to perform fine-needle aspiration biopsy and ultrasound-guided fine-needle aspiration of breast abscesses. [8] Women may prefer breast ultrasound over mammography because it is a painless procedure and does not involve the discomfort of breast compression present in mammograms.
