| Abstract: | System design and initial results are presented from a new unilateral MR-guided breast lesion localization and core biopsy system. Over 150 imaging studies, an accuracy study on phantoms with 50 localization wire deployments and 33 core biopsy trials, and 19 clinical procedures are reported. The mean spatial accuracy from the lesion center for a 20-gauge (G) needle (N = 13) was within 1.2 ± 1.4 mm (SD) and for a 14G biopsy (N = 4) 0.8 ± 1.1 mm. For sampling using a 16G core through a 14G needle, the mean accuracy was 5.6 mm (N = 2). The needle guide geometry imposed a small, calculable targeting error. For phantom measurements using the 20G device, the mean geometryinduced error was 0.73 ± 0.43 mm. However, this contribution was, on average, 42% of the mean measured 2.35 ± 1.65 mm offset. The new device design provided an accurate and simple guidance method for localization or core biopsy of MR-visible breast lesions. © 2001 Wiley-Liss, Inc. |
