摘　　要：目的 评价超声心动图、64排螺旋CT（MSCT）及电影心血管成像（CAG）对于紫绀型先天性心脏病肺血管成像的临床应用价值。方法回顾42例紫绀型先天性心脏病患者的超声心动图、MSCT、CAG影像学资料，并和手术结果对比，进行统计学分析。其中男29例，女13例，年龄11d～28岁，平均7．26岁。结果本组42例患者经手术证实肺血管共有109处畸形。超声心动图正确诊断93处畸形，符合率85．3%；漏诊误诊16处；MSCT确诊102处畸形，符合率93．6％；漏诊误诊7处畸形；CAG确诊106处畸形，符合率97．2％；漏诊误诊3处畸形。超声心动图和MSCT、CAG对比诊断符合率均有显著性差异。MSCT和CAG对比诊断符合率无显著性差异。结论MSCT对紫绀型先天性心脏病肺血管成像具有较高的临床应用价值。Objective To evaluate the accuracy of echocardiography, 64-slice spiral CT （64-slice SCT） and cineangiocardiograms （CAG） in detecting the pulmonary vessels in cyanotic heart disease. Methods 42 patients with cyanotic heart disease（29 men and 13 women;the age ranged from 11 days to 28 years, mean 7.26 years） underwent echocardiography, 64-slice SCT and CAG. The imaging data were analyzed statistically and compared with surgical findings. Results There were 109 deformities confirmed by surgery. The accurate rates of echocardiography, 64-slice SCT and CAG in the evaluation of the pulmonary vascular deformities were 85.3 % （93/109 ）, 93.6% （102/109 ） and 97.2% （106/109）, respectively. The differences among t]aem were significant, the accurate rates of 64-slice SCT and CAG were higher than that of echocardiography, but there was no differences between 64-slice SCT and CAG. Conclusion 64-slice SCT is of high accuracy in the evaluaton of the pulmonary vessels in cyanotic heart disease.
