背景本研究的目的是比较Emory Cardiac SPECT、Myovation和定量门控SPECT软件在自动测量灌注和功能性左心室（LV）定量参数、总应力评分（SSS）、灌注缺损评分、LV射血分数（LVEF）、舒张末期容积和收缩末期容积（ESV.Methods and Results）方面的差异。（99）在634名连续患者中进行了mTc-替曲膦门控SPECT研究，基于一天的应激/休息方案。参与者根据心脏大小（ESV截止值：25 mL）、灌注（SSS >/= 50%）、轻度中度受损（35-49%）和严重异常（3个亚组（组内相关系数，ICC 0.73-0.93））分为亚组。在SSS
Background. The aim of the present study was to compare Emory Cardiac Toolbox, Myovation, and Quantitative Gated SPECT software regarding the automatic measurements of perfusion and functional left ventricular (LV) quantitative parameters, summed stress score (SSS), perfusion defect score, LV ejection fraction (LVEF), end-diastolic volume, and end-systolic volume (ESV).Methods and Results. (99)mTc-tetrofosmin gated SPECT studies were performed in 634 consecutive patients based on the one-day stress/rest protocol. Participants were divided into subgroups according to heart size (ESV cut-off value: 25 mL), perfusion (SSS >/= 50%), mildly moderately impaired (35-49%), and severely abnormal (3 subgroups (intraclass correlation coefficients, ICCs 0.73-0.93).
