本文报道一例罕见的儿童先天性心脏病修复术后复杂血流动力学的综合评估，包括左心发育不全、右室双出口、大动脉转位、室间隔缺损、主动脉缩窄和全腔静脉-肺连接。基于一次测量，全心血流敏感的4D磁共振成像(MRI)能够显示多个区域血流变化，如狭窄后的螺旋形成和双动脉出口以及左、右肺的不对称血流分布。我们的研究结果表明，血流敏感的4DMRI作为一种无创、无辐射的技术，在这些儿科患者的介入后频繁随访中具有潜在的作用。J·马根。雷森。《成像》2012年；35：933937。(C)2012年威利期刊公司。
We report the comprehensive evaluation of the complex hemodynamics in a rare case of a pediatric patient after repair of congenital heart disease with multiple abnormalities including hypoplastic left heart, double outlet right ventricle, transposition of great arteries, ventricular septal defect, aortic coarctation, and total cavopulmonary connection. Based on a single measurement, whole-heart flow-sensitive 4D magnetic resonance imaging (MRI) was able to demonstrate a number of regional flow alterations such as poststenotic helix formation and asymmetric flow distributions for the double arterial outlet and to the left and right lungs. Our findings illustrate the potential role of flow-sensitive 4D MRI as a noninvasive and radiation-free technique for the frequent postinterventional follow-up in these pediatric patients. J. Magn.
