摘要
目的：评价ＭＲＩ、Ｂ超对先心病各种畸形的显示能力，并结合手术结果，比较各自的优缺点；探讨一种快速梯度回波的心脏单层面多时相、多层面单时相、多层面多时相的临床应用价值。材料与方法：５１例先心病８１个畸形经ＭＲＩ、Ｂ超检查并与手术结果对照。结果：本组经证实的８１个畸形病变中，ＭＲＩ的诊断符合率为９２％。ＭＲＩ能够显示肺动脉的全貌和发育情况以及心脏大血管的畸形，同时快速梯度回波序列（Ｆａｓｔｃａｒｄ）有利于显示小的间隔缺损和动脉导管未闭（ＰＤＡ）。结论：ＭＲＩ对先心病的诊断具有重要的诊断价值和意义。而且Ｆａｓｔｃａｒｄ与ＳＥ序列相结合能明显提高诊断效果。
Objective: To evaluate the ability, and the advantages and limitations of MRI and echocardiography in detecting congenital heart disease (CHD). To assess the role of fast gradient recalled echo sequence with cardiac triggered segmented acquisition (Fastcard) in diagnosing CHD.Materials and Methods:MRI and echocardiography were performed in 51 cases with CHD. A comparison was made between the data obtained and surgery.Results:Of 81 cases with CHD, 75(92%) could be diagnosed on MRI. Extracardiac abnormalities and pulmonary artery were well demonstrated on MRI. Fastcard imaging was superior to SE in revealing PDA and small septal defect.Conclusion:
