摘　　要：目的:探论64排螺旋CT薄层扫描加动态增强扫描在周围型小肺癌的诊断价值。方法:对CT室近2年来诊断的31例周围型小肺癌(SPLC)患者进行回顾,并统计分析。结果:对数据进行分析统计,薄层扫描加动态增强扫描在分叶征(x2=6.331,P=0.012)、细支气管气相(x2=4.048,P=0.044)、血管集束征(x2=4.865,P=0.027)、短毛刺征(x2=16.452,P=0.000)显示率明显高于平扫,有统计学意义(P<0.05),而胸膜凹陷征(x2=0.706,P=0.401)、棘突征(x2=1.038,P=0.308)、空泡征(x2=0.540,P=0.463)显示率较高,但无统计学意义(P>0.05)。结论:64排螺旋CT薄层扫描加动态增强扫描在周围型小肺癌的诊断中具有极高的应用价值。Objective： To investigate the value of 64-slice spiral CT plus dynamic contrast- enhanced CT scanning in the diagnosis of small peripheral lung cancer （SPLC）. Methods： The data of 31 SPLC patients diagnosed in the past two years were retrospectively analyzed. Results： Thin slice scanning plus dynamic enhanced scanning showed significantly higher rates of lobulation （.v2=6.331, P=0.012）, bronchioles vapor （x2=4.048, P=0.044）, vessel convergence sign （x2=4.865, P=0.027） and short sentus （x2=16.452, P=0.000） than unenhanced scanning. Both thin slice scanning plus dynamic enhanced scanning and unenhanced scanning showed higher rates of pleural indentation （x2=0.706, P=0.401）, spinous process syndrome （x2= 1.038, P=0.308） and vacuole sign （x2=0.540, P=0.463）,but the differences between them were not significant （P〉0.05）. Conclusion： Sixty-four-slice spiral CT plus dynamic contrast-enhanced CT is of great value in the diagnosis of SPLC.
