摘要
目的探讨ＭＲＩ诊断先天性右位心并心内复杂畸形的实用价值。方法应用ＭＲＩ心电门控多层自旋回波序列及磁共振电影，对４例先天性心脏病右位心并心内复杂畸形进行多轴位多层面断层扫描，并将检查结果与经手术证实的心脏病理解剖进行对比。同时对心脏ＭＲＩ扫描与超声心动图彩色血流显像的诊断，作进一步比较及评估。结果３例右位心（右旋心）其主要心内结构的改变为：１例Ｆａｌｏｔ四联症（ＴＯＦ）；１例右室双出口（ＤＯＲＶ）、肺动脉骑跨、左上腔静脉残存；１例大动脉左异位（ＬＭＧＡ）、房间隔缺损（ＡＳＤ）、室间隔缺损（ＶＳＤ）、肺动脉狭窄（ＰＳ）、左上腔静脉残存；１例镜面右位心并内脏转位、ＶＳＤ、ＰＳ、双上腔静脉。结论ＭＲＩ对先天性心脏病右位心并心内复杂畸形可以获得准确的病理解剖诊断，借此可说明ＭＲＩ诊断复杂心内畸形有较高的实用价值，它与心血管造影及超声心动图各具独特优势。
Purpose To evaluate clinical usefulness of MRI in diagnosing dextrocardia with complex cardiac anomalies. Methods 4 patients underwent MRI examination with spin echo (SE)ECG gated and cineMRI.These cases were also evaluated with doppler echocardiography and confirmed by operation. Results MRI diagnosis was in accordance with the operative findings. 3 cases were complicated by TOF, DORV, LMGA, VSD, and PS. 1 case of mirror dextrocardia had concomitantly VSD, ASD, PS, and DSVC. Conclusion MRI is one of the optimal imaging techniques in diagnosing dextrocardia with complex heart anomalies. Conventional SE in combination with cineMRI greatly increases the diagnostic efficacy. Cardioangiography, echocardiography and MRI, each having its own advantage, are complementary and not exclusive.
