目的 :探讨螺旋CT(SCT)对中央型肺癌术前分期的价值。方法 :经手术和病理证实的支气管肺癌共 88例 ,将SCT检查结果与病理进行对照分析。结果 :螺旋CT分期和术后病理符合率为 :Ⅰ期 83 .3 % ,Ⅱ期 87.0 % ,ⅢA期 94.1% ,ⅢB期 95 .0 % ,Ⅳ期 10 0 % ,总体符合率 92 .0 %。螺旋CT诊断淋巴结转移的敏感性 82 .9% ,特异性 83 .3 % ,准确率83 .0 %。结论 :螺旋CT对中央型肺癌术前分期有较高的准确性 ,对指导临床制定治疗方案具有较高价值
Objective: To investigate the value of spiral CT (SCT) in preoperative staging of central lung cancer. Methods: A total of 88 patients with bronchogenic carcinoma confirmed by surgery and pathology were analyzed by SCT and pathology. Results: The coincidence rates of spiral CT and postoperative pathology were 83.3% in stage Ⅰ, 87.0% in stage Ⅱ, 94.1% in stage ⅢA, 95.0% in stage ⅢB, 100% in stage Ⅳ, and the overall coincidence rate was 92.0% . The sensitivity of spiral CT in diagnosing lymph node metastasis was 82.9%, the specificity was 83.3%, and the accuracy was 83.0%. Conclusion: Spiral CT has a higher accuracy for the preoperative staging of central lung cancer, and has higher value for guiding the clinical treatment plan
