Three-dimensional surface reconstruction images of the heart and great vessels can be produced from contiguous sequences of ECG-triggered MR scans in patients with congenital heart disease. The methods allow separation of the epi- and endocardial surfaces and definition of the enclosed blood volumes on a slice-by-slice basis. Surface reconstruction images have value in communicating the results of MR examinations to clinicians in cases where cardiac morphology is unusually complex; in depicting intracardiac defects, size, and location; and in aiding the study of pulmonary venous drainage. This method can be practical in studying cardiac morphologic abnormalities and especially in planning cardiac surgery.
先天性心脏病患者的心脏和大血管三维表面重建图像可由心电图触发的磁共振扫描的连续序列生成。这些方法能够逐片分离心外膜和心内膜表面,并确定封闭的血容量。在心脏形态异常复杂的情况下,表面重建图像对于向临床医生传达磁共振检查结果、描绘心内缺损、大小和位置以及辅助肺静脉引流研究具有重要价值。该方法在研究心脏形态异常方面具有实用性,尤其在心脏手术规划中。
