摘　　要：目的探讨64排螺旋CT多平面重建(MPR)技术在诊断肺原位腺癌中的应用价值。方法回顾性分析30例经病理证实为原位腺癌的CT征象,利用三维成像软件行多平面重建,比较横断面图像与MPR图像对原位腺癌基本征象的显示率。结果与横断图像比较,MPR重建图像对磨玻璃密度结节、分叶征、毛刺征的显示率(100.00%、80.00%、26.67)有明显提高(P<0.05),对胸膜凹陷征、空泡征、血管集束征的显示率(30.00%、10.00%、30.00%)无明显提高(P>0.05)。结论 MPR重建方法较常规横断位扫描能更准确地显示原位腺癌形态特征,对其诊断具有重要价值。Objective To explore the value of muti-planar reconstruction（MPR）with 64-slices spiral CT in diagnosing adenocarcinoma in situ（AIS）.Methods The CT manifestations of pathologically-proved AIS were analyzed.MPR images were obtained with 3Dreconstruction software,and the findings on the MPR images were compared with primary crosssectional images.Results Compared with cross-sectional images,the display rates of ground glass opacity,lobulation,spiculation were significantly better on the reconstructed images（P〈0.05）,whereas,the display rates of pleural indentation,vascular convergence,vacuole sign were no significantly different（P〉0.05）.Conclusion MPR with spiral CT can show the morphology of AIS more precisely than cross-sectional image,which could benefit the diagnosis of AIS.
