A guiding attachment is described that transforms a conventional magnetic resonance (MR) imaging surface coil into a stereotaxic biopsy unit. Eight patients, aged 38-66 years (mean, 54 years), with suspect breast lesions detected exclusively at contrast material-enhanced MR imaging underwent MR-guided needle biopsy with this unit. Diagnostic material was successfully aspirated in all patients (four carcinomas, three fibroadenomas, and one intraductal hyperplasia), and the diagnosis was subsequently confirmed at surgical biopsy. This technique promises to increase the diagnostic specificity for lesions seen solely at MR imaging.
本文描述了一种导向附件，它可将传统的磁共振（MR）成像表面线圈转变为立体定向活检装置。8例年龄在38 - 66岁（平均54岁）、仅在对比剂增强MR成像中发现可疑乳腺病变的患者接受了该装置引导下的MR引导穿刺活检。所有患者均成功获取诊断性材料（4例为癌，3例为纤维腺瘤，1例为导管内增生），随后手术活检证实了诊断。该技术有望提高仅在MR成像中发现的病变的诊断特异性。
