摘　　要：在最近几十年中,心脏再同步化治疗作为一种新的治疗策略,在临床上应用于终末期心力衰竭患者。门控心肌灌注显像(GMPI)的相位分析技术可以很好地评价左心室机械不同步性,且表现出自动控制处理、重复性良好,并能得到灌注和预后信息。应用门控心肌核素显像相位分析技术指导CRT已成为国际上的热点,综述分析GMPI时相分析参数相位直方图宽带、相位标准差在心力衰竭患者心脏再同步化治疗及预测疗效上的临床应用价值。In recent decades,cardiac resynchronization therapy is a new treatment strategy for the patients with end-stage heart failure in clinical application. The phase analysis of the gated myocardial perfusion imaging( GMPI) can be a good evaluation of left ventricular mechanical synchronicity and show that the automatic control process,good repeatability,and can get perfusion and prognostic information. Myocardial viability and left ventricular systolic synchrony can be assessed by gated positron emission tomography( PET). Application of phase analysis of the gated myocardial perfusion imaging technology to guide CRT has become a hot research hotspot,this article analyzes phase analysis parameters of the GMPI: phase histogram bandwidth( BW),phase standard deviation( SD) on the value of cardiac resynchronization therapy and predicting prognosis.
