【摘要】 目的探讨CT导向经皮针吸活检对恶性纵隔肿块的诊断意义。方法随机选择2003年10月—2007年12月作者所在医院疑为纵隔肿瘤(直径≥15mm)的患者76例,在CT扫描监控下,使用国产秦氏活检针进行针吸活检(FNB)与相应的病理细胞学检查。结果全部病例均经手术(43例)与1年以上随访(33例)证实。FNB对恶性纵隔肿瘤诊断的敏感性为90.5%(57/63),特异性为84.6%(11/13),准确性为89.5%(68/76)。结论CT导向经皮FNB是一简便而又可靠的诊断方法,对纵隔肿瘤恶性肿块的诊断有重要的参考价值。更多还原

【Abstract】 Objective To evaluate the diagnostic significance of CT guided percutaneous fine needle biopsy (FNB) of malignant mediastinal masses. Methods Seventy-six patients were randomly chosen from all the patients suspected of mediastinal neoplasm(diameter≥15 mm).Pecutaneous fine needle biopsy was performed under CT monitoring, and then pathologic-cytological examination was made accordingly.Results Forty-three cases were confirmed by operation and 33 cases by more than 1 year follow-up. The sensitivity, specificity and accurate rate of FNB on the diagnosis of mediastinal neoplasm were 90.5%, 84.6% and 89.5% respectively.Conclusion CT guided percutaneous fine needle aspiration biopsy of mediastinal masses is useful, less expensive and effective technique for diagnostics of malignant mediastinal tumor.更多还原
