摘　　要：目的评估64层螺旋CT心轴位像对先天性心脏病主动脉骑跨程度的诊断价值。方法回顾性分析195例先天性心脏病患者的64层螺旋CT检查资料,其中男101例,女94例,年龄5个月～30岁,平均(7.9±7.5)岁,均使用PhilipsBrilliance64层螺旋CT机双期扫描和回顾性心电门控。前期123例采用体轴法测评骑跨率,后期72例用心轴位像法测评。所有195例均接受手术治疗。结果以术后诊断为标准,64层MSCT的心轴位像法对主动脉骑跨程度测评的符合率为100%(72/72),优于体轴法符合率(94.31%,116/123)。结论64层螺旋CT心轴位像对先天性心脏病主动脉骑跨程度判断有重要意义。Objective To evaluate the degree of aortiac overriding in congenital heart disease with cardiac-axis image of 64-slice CT.Methods Retrospective analysis of 64-slice CT examination data of 195 patients with congenital heart diseases,including 101 males,94 females,aged 5 months to 30 years,with the average of（7.9±7.5）years were performed.All patients underwent dual-phase and retrospective ECG-gated CT scanning with Philips Brilliance 64 CT,and all received surgical treatment after CT examination.Aortiac overriding rate were measured and calculated on body-axis images in early 123 patients,and on cardiac-axis images in late 72 patients.Results Taking the surgical diagnosis as diagnosis standard,the coincidence rate of aortic overriding rate on cardiac-axis images was 100%（72/72）,better than that of body-axis images（94.31%,116/123,P〈0.05）.Conclusion Cardiac-axial images of 64-slice CT has important significance to evaluate degree of aortic overriding in congenital heart diseases.
