Fast MRI-Guided Vacuum-Assisted Breast Biopsy: Initial Experience

Abstract

MRI-guided vacuum-assisted biopsy is a fast, safe, and accurate alternative to surgical biopsy for breast lesions detected on MRI.

Vacuum-assisted biopsies under MR guidance: results of 72 procedures

“…Our 98% rate of technically feasible biopsies correlates with these results [17][18][19][20][21][22][23][24].…”

“…Ductal non-mass-like enhancements were malignant in 8 of the 23 lesions (35%). This rate exceeds the 26% rate of malignancy reported in ductal enhancement by Liberman et al [19]. Segmental enhancement corresponded to a malignant lesion in 50% of the cases.…”

“…Compared with using the 9-gauge ATEC Suros device employed by Liberman et al, the duration of our procedure was longer, with an estimated median of 72 min, versus a mean time of 33-38 min with the 9-gauge ATEC Suros device [19][20][21]. In a previous study using the same 10-gauge VACORA device as ours, the mean duration of the procedure was comparable, an estimated 65 min, ranging from 52 to 87 min [28].…”

“…A mean of 8-14 specimens were collected with the same 10-gauge device [24,28]. A median of 8-12 specimens were reported when using the 9-gauge ATEC Suros device [19,21]. In an interdisciplinary consensus on the Fig.…”

“…It is a safe and accurate technique routinely performed under stereotactic and sonographic guidance [15,16]. Several studies have shown promising results of breast VAB under MRI guidance [17][18][19][20][21][22][23][24].…”
