EVALUATION OF FONTAN PATHWAY HEMODYNAMICS BY MRI PHASE VELOCITY IMAGING

本研究的目的是通过mri相速度评价。 影像技术，无论改良Fontan手术结果如何 在比经典Fontan更节能的流动模式中 手术并提供血流动力学的基线特征 当前外科技术的结果，未来的外科手术 修改是可以比较的。新发展的磁共振成像技术 相速度成像允许三维血流模式 用图形来描绘。

The purpose of the study is to evaluate, by means of MRI phase velocity imaging techniques, whether or not the modified Fontan procedure results in a more energy efficient flow pattern than does the classic Fontan operation and to provide a baseline characterization of the hemodynamic results of current surgical techniques against which future surgical modifications can be compared. The newly developed technique of MRI phase velocity imaging allows for three dimensional blood flow patterns to be depicted graphically.
