Abstract

Cine MRI and VEC MRI can be used to quantitate the physiology of the heart and great vessels in patients with CHD. This information can be a valuable adjunct to anatomical imaging for preoperative planning as well as postoperative monitoring. Some important clinical applications of quantitative cardiovascular functional MRI include measurement of ventricular masses, stroke volumes, and ejection fractions; estimation of shunts and valvular regurgitation; assessment of collateral blood flow and pressure gradients in aortic coarctation; and postsurgical evaluation of conduit blood flow and pressure gradients.

摘要

电影磁共振成像（Cine MRI）和速度编码磁共振成像（VEC MRI）可用于对冠心病患者的心脏和大血管生理功能进行定量分析。这些信息对于术前规划的解剖成像以及术后监测而言，是一项很有价值的辅助手段。定量心血管功能磁共振成像的一些重要临床应用包括测量心室质量、每搏输出量和射血分数；评估分流和瓣膜反流；评估主动脉缩窄时的侧支血流和压力梯度；以及对术后管道血流和压力梯度进行评估。
