摘要:
临床心功能评价常规且重要,心脏磁共振(CMR)电影序列可获得心脏全心动周期的动态图像。从借鉴超声心动图检查的基础上不断发展,CMR已建立了一套评估心功能的扫描序列和评价指标系统,包括射血分数、心室质量指数、应变、室间隔曲率比、右房室瓣环收缩期位移、血管顺应性等。认识和掌握这些指标的原理、意义及适应证有助于优化扫描序列和及时有效做出诊断,对临床治疗和预后评估有重要意义。本文就CMR评价心功能技术、指标的临床应用现状和进展进行综述。

Abstract:
Clinical evaluation of cardiac function is routine and important. Cardiac magnetic resonance (CMR) cine sequence can obtain dynamic images of the whole cardiac cycle. Based on echocardiographic techniques, CMR has been used to establish a set of scanning sequences and an evaluation index system to evaluate cardiac function, including ejection fraction, ventricular mass index, strain, interventricular septum curvature ratio, tricuspid annular plane systolic excursion and vascular compliance. Understanding the principles, significance and indications of these indicators is helpful to optimize the scanning sequence and make timely and effective diagnosis, which is of great significance for clinical treatment and prognosis evaluation. This review sums up the status and progress of clinical application of CMR in evaluation of cardiac function.
