To evaluate the efficacy of ultrasound (US)-guided automated large-core percutaneous needle breast biopsy, biopsy of 181 ultrasonographically suspicious breast lesions was performed by using a long-throw biopsy gun and 14-gauge needles with continuous US guidance. A "freehand" technique with either 5.0- or 7.5-MHz linear-array transducers was used. Needle core diagnoses were compared with surgical diagnoses in the 49 lesions subsequently surgically excised. The remaining 132 cases were followed for 12-36 months. Agreement between needle-core and surgical diagnoses in the 49 lesions was 100%. This group included 34 cancers (28 infiltrating ductal, two mucinous, one mixed infiltrating ductal and lobular, and one each of intraductal, infiltrating lobular, and tubular carcinoma). To date, no cancers have been found in the other 132 cases. The procedure time averaged 20 minutes, and no complications occurred. With an accuracy approaching that of excisional biopsy, US-guided needle core biopsy provides an alternative to surgery.
为评估超声（US）引导下自动大型芯经皮乳腺穿刺活检的疗效，使用长射程活检枪和14号针在连续超声引导下对181个超声可疑乳腺病变进行活检。采用“徒手”技术，使用5.0或7.5MHz线阵换能器。对随后手术切除的49个病变的针芯诊断结果与手术诊断结果进行比较。其余132例患者随访12至36个月。49个病变的针芯诊断与手术诊断的一致性为100%。该组包括34例癌症（28例浸润性导管癌、2例黏液癌、1例浸润性导管癌和小叶癌混合型，以及导管内癌、浸润性小叶癌和管状癌各1例）。迄今为止，其他132例患者未发现癌症。手术时间平均为20分钟，未发生并发症。超声引导下针芯活检的准确性接近切除活检，为手术提供了一种替代方法。
