【摘要】 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。更多还原

【Abstract】 The objective of this study was to evaluate the diagnostic significance of CT guided percutaneous automated cutting needle biopsy(ACNB)of malignant mediastinal masses.Between October 2003 and December 2007,85 percutaneus CT-guided biopsies of mediastinal lesions(D≥15 mm)were performed on 71 patients under local anesthesia.All the patients were evaluated pathologically at operative resectic(46 cases),autopsy(3 cases)and follow up(22 cases)afterward.The overall sensitivity,specificity and accurate rate were 94%,92% and 93% respectively.In conclusion,CT guided percutaneous needle cutting biopsy of mediastinal masses is a useful,less expensive and effective technique for diagnosis of malignant mediastinal tumor.更多还原
