Twelve patients more than 8 years of age with complex congenital heart disease were evaluated prospectively with nuclear magnetic resonance (NMR) imaging and with echocardiographic and angiographic imaging techniques. The subpulmonary region, main pulmonary artery, right and left pulmonary arteries, and aorticopulmonary shunts were clearly visualized by means of NMR imaging in all patients. Angiography defined the subpulmonary region and main pulmonary artery in all patients, the right and left pulmonary arteries along their length in 11 of 12 patients, and aorticopulmonary shunts in seven of eight patients. Except for the right pulmonary artery, echocardiography defined the remaining structures in less than or equal to 50% of patients. Measurement of the pulmonary artery diameters on NMR images correlated well with the angiographic measurements of both the left (r = 0.96) and right (r = 0.94) pulmonary arteries. These results suggest that NMR imaging may be the preferable noninvasive imaging technique for defining the anatomy of the subpulmonary region, main and left pulmonary arteries, and aorticopulmonary shunts in older patients with congenital cardiovascular disease and that it compares well with the angiographic standard.
对12名8岁以上患有复杂先天性心脏病的患者进行了前瞻性评估，采用核磁共振（NMR）成像以及超声心动图和血管造影成像技术。在所有患者中，通过NMR成像均能清晰显示肺下区域、主肺动脉、左右肺动脉以及主动脉-肺动脉分流。血管造影在所有患者中明确了肺下区域和主肺动脉，在12例患者中的11例明确了左右肺动脉的全长，在8例患者中的7例明确了主动脉-肺动脉分流。除右肺动脉外，超声心动图在不到或等于50%的患者中明确了其余结构。NMR图像上肺动脉直径的测量结果与左（r = 0.96）、右（r = 0.94）肺动脉的血管造影测量结果相关性良好。这些结果表明，对于先天性心血管疾病老年患者，NMR成像可能是用于明确肺下区域、主肺动脉和左肺动脉以及主动脉-肺动脉分流解剖结构的首选非侵入性成像技术，并且与血管造影标准相比效果良好。
