先天性心脏病磁共振诊断(附1000例报道)

MR examination of congenital heart disease

目的:评价磁共振对先心病的诊断价值和实用检查技术。材料与方法:1000例先心病作了磁共振检查,扫描序列为自旋回波T1WI序列,梯度回波电影序列和造影增强的磁共振血管成像序列。结果:对于心外大血管异常磁共振诊断符合率为96.5%,对于心内结构异常磁共振诊断符合率为85.6%。结论:磁共振对先心病,特别是伴有心外大血管异常的先心病,复杂先心病和手术后先心病的诊断有很高的实用价值,其中造影增强的磁共振血管成像序列必不可少。

Objective: To evaluate the diagnostic value and scan technique of MRI in congenital heart disease. Materials and Methods: One thousand patients with congenital heart disease underwent MR examination. SE T1W sequence, gradient echo cine sequence and contrast enhanced MR angiographyCE-MRA were performed. Results: 96.5% of extracardiac malformations and 85.6% of intracardiac malformations were diagnosed correctly by MR. Conclusion: MR is very helpful for congenital heart disease. CE-MRA is one of the most useful sequence.
