婴幼儿法乐四联症的MRI诊断(附30例分析)

MRI Diagnosis of Fallot's Tetralogy in Infants

目的 探讨先天性心脏病婴幼儿法乐四联症的MRI诊断价值。材料与方法 分析 30例婴幼儿法乐四联症MRI所见 ,并与心血管造影和超声心动图比较。结果 30例室间隔及其缺损均在横断面扫描显示最佳 ,2 5例主动脉骑跨在冠状面扫描显示清晰 ,5例显示不清。 30例肺动脉主干及右肺动脉则在矢状面扫描较清楚 ,其中 4例还显示出第三心室。结论 MRI检查安全、无创 ,优于心血管造影 ;能对各房室连接及心肌厚度多方位、多手段检查且显示良好 。

Objective To assess the diagnostic value of MRI for Fallot's tetralogy in infants.Materials and Methods MRI findings in 30 infants with Follot's tetralogy were analyzed, and the signs were compared with the results of color Doppler echocardiography and angiocardiography.Results Both the ventricular septum and its defect were best demonstrated on transverse scans, while overriding aorta was best seen on coronal scans and pulmonary trunk and right pulmonary artery on sagittal scans. The hypertrophic right ventricle could be well displayed on all the above scans.Conclusion Being a safe, non invasive, effective and reliable method, MRI is superior to angiocardiography and Doppler echocardiography in diagnosing Fallot's tetralogy in infants.
