多层螺旋CT对周围型小肺癌的诊断(附40例分析)

Multi-slice spiral CT Diagnosis of peripheral small Lung Cancer(Analysis of 40 Cases)

目的探索周围型小肺癌的多层螺旋CT征象,评价肺癌的多层螺旋CT诊断准确性。方法对40例经病理证实的周围型小肺癌多层螺旋CT片进行回顾性分析研究。结果40例周围型小肺癌中,腺癌32例、鳞癌5例、小细胞癌3例.。周围型小肺癌的MSCT主要征象为:深分叶30例、棘状突起25例、空泡征5例、胸膜凹陷征8例、以及血管集束征7例。结论在周围型小肺癌诊断中,多层螺旋CT征象起着重要作用,多层螺旋CT扫描对诊断周围型小肺癌具有很大价值.

Purpose: To explore multi-slice spiral CT (MSCT) manifestion of peripheral small lung cancer (PSLC) and evaluate CT diagnostic accuracy of MSCT in lung cancer. Materials and methods:MSCT signs of 40 cases of pathologically proved lung cancer were in were studied retrospectively. Results: PSLC of 40 cases had one of the following patterns: adenocarcinoma(32), squamous carcinoma(5), small cell carcinoma(3). Among 40 cases with PSLC,main sign on CT were found to be deep lobulation sign in 30 ,marginal speculated sign in 25 ,vacuole sign in 5 , pleural indentation sign in 8, and vascularnotch sign in 7 .Conclusion:MSCT signs of PSLC play an important role in the diagnose ,it can improve the accuracy to diagnose PSLC.
