64排螺旋CT评价中央型肺癌气管、支气管及肺门血管侵犯的应用研究

目的 探讨64排螺旋CT血管成像诊断中央型肺癌（CLC）气管、支气管及肺门血管侵犯的准确性.方法 收集43例临床确诊的CLC患者64排螺旋CT检查结果,并以病理诊断结果为参照标准判断其准确性.结果 43例患者气管、支气管受侵,CT诊断气管、主支气管、叶支气管、近端段支气管的准确性分别为100%、97.67%、96.74%、88.37%.38例患者肺门血管受侵,CT诊断肺门血管受侵和可疑受侵的准确性分别为88.23%、75.00%.结论 64排螺旋CT能比较准确地显示CLC气管、支气管、肺门气管侵犯的情况.

Evaluation of invasion of centrally located lung cancer to the trachea, bronchi, and hilar vessels using 64-slice CT

Objective To explore the accuracy of 64-slice computed tomography (CT) for evalu- ating invasion of centrally located lung cancer to the trachea, bronchi, and hilar vessels. Methods Forty- three patients who had undergone CT scans were collected. Pathological findings were documented and regarded as a gold standard for all the patients. Results Tracheal and/or bronchial invasion were found in all the patients. The accuracy of CT scans was 100% on tracheal invasion, 97.67% on primary bronchial invasion, 96.74% on lobe bronchial invasion, and 88.37% on proximal segmental bronchial invasion. Hilar vascular invasion was found in 38 patients, with an accuracy of 88.23% on definite invasion and 75.00% on suspicious invasion. Conclusions 64-slice CT has a high accuracy in demonstrating invasion of centrally located lung cancer to the trachea, bronchi, and hilar vessles.
