Vacuumassisted biopsy is the technique of first choice for MR-guided breast biopsy (Liberman et al. 2005; Kuhl 2007). 2 Large-Core Biopsy Systems: Overview Currently one single large-core radiofrequency biopsy system and four vacuum-assisted multiple-core biopsy systems are in routine use for breast diagnosis and excision. All of the VAM systems are suitable for use under ultrasound, R. Wilson and S. Kavia stereotactic (upright and prone table), and MR imaging guidance; the single intact biopsy system is described as being suitable for ultrasound and X-ray stereotactic-guided biopsy.

Air bubbles are seldom a problem since the Mammotome is a singleinsertion technique, which is an advantage compared to other techniques that use coaxial needles and require multiple insertions. When a tissue fragment fails to be retrieved or is smaller than expected, there is a chance that it is fragmented. In this case, we can do a “dry run,” which means that the needle is closed without cutting to try to retrieve the sample. The procedure requires some operator experience in US of the breast, as well as in performing guided biopsies.

Some also advocate the use of longer-acting local anesthetic in the deeper tissues around the target lesion to reduce postprocedure anesthesia. All but the Vacora system allow for further injection of local anesthetic through the biopsy probe into the target area (Fig. 22b). This can be done as a matter of routine before the biopsy is commenced, particularly for stereotactic procedures when the probe has been placed and displacement of the lesion is then less likely to occur. The EnCor device has a specific program for delivering local anesthetic around the area to be biopsied.
