摘　　要：目的探讨CT导向经皮针刺切割活检对恶性纵隔病变的诊断意义。方法2003年10月—2006年12月期间随机选择临床疑为纵隔肿瘤(直径≥15mm)的71例患者,在CT扫描监控下,使用MD-TECH活检枪和与之配套的活检针进行78例次纵隔肿块自动切割活检(ACNB)与相应的病理细胞学检查。结果经手术(46例)、尸检(3例)与1年以上随访(22例)证实:敏感性为93.8%(30/32),特异性为92.3%(36/39),准确度为93.0%(66/71)。结论CT导向经皮纵隔病变ACNB是一种简便而又可靠的诊断方法,对纵隔肿瘤良、恶性的诊断有重要的参考价值。Objective To evaluate the diagnostic significance of CT guided percutaneous automated cutting needle biopsy （ACNB） of malignant mediastinal masses. Methods Between Oct 2003 and Dec 2006, 78 percutaneous CT-guided biopsies of mediastinal lesions were performed on 71 patients under local anesthesia. After supine or prone posistioning, CT scan was performed with a 5 mm thickness and a 5 mm interval. The mediastinal masses （≥15 mm） was punctured with a 16-gauge or 18-gauge （through non-aerated lung） automated cutting needle under intermittent CT monitoring and minium of 2--3 cores were obtained. Results All patients were evaluated pathologically at operative resectic （46）, autopsy （3） or follow up （22） afterward. The overall sensitivity, specificity and accurate rate were 93.8G （30/32）, 92.3% （36/39） and 93.0% （66/71）, respectively. Conclusion CT guided percutaneous needle biopsy of mediastinal masses is a useful, and effective technique for diagnosis of malignant mediastinal masses.
