多层螺旋CT在复杂先天性心脏病临床诊断应用的可行性

放射影像科陈正光ZG。Chen，Ph.D.,MDZGCHEN,MD,PhD目的尽可能的用标准体位来显示心脏的解剖和畸形之所在。

横轴位－其他轴位形成的基础长轴位－RV，orLV平行于室间隔四腔像短轴像

RVOT和LVOT（所谓三腔像）尽可能地去认识畸形所致的血流动力学所致的改变。ZGCHEN,MD,PhDZGCHEN,MD,PhD多排螺旋CTZGCHEN,MD,PhD08’RSNAPulmonaryAtresia:AssessmentofPulmonaryArteryandPulmonaryBloodSupplywithMDCTEvaluationofAnomalousPulmonaryVenousDrainageinPatientswithComplexCongenitalHeartDiseasesUsingMultidetectorComputedTomography(MDCT)TheValueofMDCTforPredictionofPostoperationLowCardiacOutputSyndromeinPatientswithCyanoticCongenitalHeartDiseaseEvaluationonTetralogyofFallot(TOF)UsingMultidetectorComputedTomography(MDCTTheIncrementalDiagnosticYieldofMDCTinPatientswithComplexCongenitalHeartDisease
