摘　　要：目的评价磁共振成像（MRI）对复杂型先天性心脏病的诊断价值。方法对2l例复杂型先天性心脏病患者的MRI资料进行诊断分析，记录心血管畸形数目，以外科术后诊断（17例）或超声、心导管与心脏CT两种或以上检查的一致诊断（4例）作为参考标准，评估其诊断价值。结果2l例患者共63个主要心脏大血管异常，MRI检出61个，正确诊断率为96．8％（61／63）；误诊3个，分别为：漏诊房间隔缺损、主要体肺动脉侧支各1个和动脉导管残端误诊为动脉导管未闭1个。结论MRI对复杂型先天性心脏病正确诊断率高，可以作为心脏超声检查的重要补充检查手段。Objective To evaluate the value of MRI in the diagnosis of complex congenital heart disease. Methods Twenty-one patients with complex congenital heart disease, who had undergone MRI examination were enrolled in this research. The MRI data of every patient was analyzed and abnormalities of anatomy was counted by two experienced cardiovascular radiologist. Surgical diagnosis （17 cases） or consistent diagnosis （4 cases） of ultrasonic, cardiac catheter and cardiac CT was regarded as reference standards. Accuracy and misdiagnosis rate were obtained. Results Twenty-one patients had 63 main abnormalities,61 malformations was found by MRI examination, the diagnostic accuracy was 96. 8%, and the misdiagnosis rate was 4. 8% （ 1 atrial septal defect（ASD） and 1 major aorta pulmonary collateral arteries（MAPCAS） were missed, 1 arterial duct stump was misdiagnosed as patent ductus arteriosus （PDA）. Conclusion MRI has excellent diagnostic accuracy on complex congenital heart disease,it is another good noninvasive cardiac examination method beside ultrasonic.
