摘　　要：目前,药物负荷单光子发射计算机断层成像门控心肌灌注显像(SPECT G-MPI)是临床测量左心室射血分数(LVEF)储备的常用检查方式。LVEF储备是反映左心室收缩潜力的参数,测量的准确性与SPECT G-MPI检查所用显像剂、心脏负荷药物、采集条件及个体差异等多方面因素相关。了解把握药物负荷SPECT G-MPI测定LVEF储备的影响因素,可为临床实践中LVEF储备的准确测定提供参考。At present,gated single-photon emission computed tomography myocardial perfusion imaging(SPECT GMPI)with vasodilator stress agents is a commonly used diagnostic method for measuring left ventricular ejection fraction(LVEF)reserve in the clinical practice.LVEF reserve is a parameter that reflects the potential of left ventricular contrac tion.The accuracy of measurement is related to various factors such as the radioactive tracers used in SPECT G-MPI exami nation,vasodilator stress agents,acquisition conditions and patients'differences.Understanding and grasping the influ encing factors of SPECT G-MPI with vasodilator stress agents can provide reference for accurate determination of LVEF re serve in the clinical practice.
