为了探讨CT导向经皮针刺切割活检对恶性纵隔病变的诊断意义,2003-10-2007-12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85次纵隔肿块自动切割活检与相应的病理细胞学检查。结果:经手术(46例)、尸检(3例)与>1年随访(22例)证实:敏感性为94%(30/32),特异性为92%(36/39),准确度为93%(66/71)。初步研究结果提示,CT导向经皮纵隔病变AC-NB是一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。
To investigate the significance of CT-guided percutaneous needle biopsy in the diagnosis of malignant mediastinal lesions, 71 patients with suspected mediastinal tumors (diameter≥15mm) were randomly selected and monitored under CT scan with MD -TECH biopsy gun and its accompanying biopsy needle for 85 mediastinal mass auto-biopsy and the corresponding pathological cytology. Results: The results of surgery (46 cases), autopsy (3 cases) and follow-up> 1 year (22 cases) showed that the sensitivity was 94% (30/32) and the specificity was 92% (36/39) 93% (66/71). Preliminary results suggest that CT-guided percutaneous mediastinal lesions AC-NB is a simple and reliable diagnostic method for the diagnosis of benign and malignant mediastinal tumors have important reference value.
