Eleven patients with a total of 17 palliative systemic-pulmonary artery shunts underwent evaluation by electrocardiogram-gated magnetic resonance imaging (GMRI). GMRI successfully imaged 11 of 17 shunts (65%), including five of nine Blalock-Taussig shunts, four of six Glenn shunts, and both aortopulmonary shunts. All shunts except for the Waterston were imaged on coronal sections during end-systole. The single Waterston shunt was seen on sagittal and transverse scans. Shunt localization and identification were facilitated by obtaining multiple, contiguous sections through the body. Glenn shunts could be imaged entirely in one section, although multiple sections were required to locate the correct plane. Blalock-Taussig shunts generally required multiple sections to image different segments of the shunt. Both aortopulmonary shunts were seen as direct side-to-side connections of the aorta and pulmonary artery. GMRI permitted assessment of the size, course, patency, and distribution of systemic-pulmonary artery shunts as well as the size and morphology of the proximal pulmonary arteries. We conclude that GMRI is a useful, noninvasive method for imaging the anatomy of systemic-pulmonary artery shunts.
11例共17处姑息性体肺分流术患者接受了心电图门控磁共振成像（GMRI）评估。GMRI成功对17处分流术中的11处（65%）进行了成像，包括9处Blalock-Taussig分流术中的5处、6处Glenn分流术中的4处以及2处主肺动脉分流术。除Waterston分流术外，所有分流术均于收缩末期在冠状位成像。单一的Waterston分流术在矢状位和横断位扫描中可见。通过获取穿过身体的多个连续层面，便于分流术的定位和识别。Glenn分流术虽通常需要多个层面来确定正确平面，但可在一个层面内完整成像。Blalock-Taussig分流术一般需要多个层面来对分流术的不同节段进行成像。两处主肺动脉分流术均表现为主动脉与肺动脉的直接侧侧连接。GMRI能够评估体肺分流术的大小、走行、通畅情况及分布，以及近端肺动脉的大小和形态。我们得出结论，GMRI是一种用于体肺分流术解剖成像的有用的非侵入性方法。
