Abstract

Objectives: The aim of this study was to analyze the systolic part of the left ventricular (LV) volume curve obtained by gated myocardial perfusion imaging with the formula used in exponential decay and to investigate the clinical value of the results.

Methods: One hundred fifty eight patients were retrospectively enrolled in the study. The study group was divided into three groups as normal, ischemia, and infarct. The systolic portion of the LV volume curve was also analyzed using the exponential decay formula. The scintigraphic parameter obtained using this formula is called the ejection constant (Ec).

Results: The Ec results were 1.8±0.8, 2.7±0.9, 3.5±1 in infarct, ischemia, and normal groups, respectively, and the difference in Ec results between the groups was statistically significant (p≤0.001).

Conclusion: It appears that Ec may play a clinical role as a scintigraphic parameter in the evaluation of systolic functions of the left ventricle.

左心室收缩功能的不同闪烁透视图-1。

目的：本研究的目的是用指数衰减公式分析门控心肌灌注成像获得的左心室（LV）容积曲线的收缩部分，并探讨其临床价值。方法：对158例患者进行回顾性研究。研究组分为正常组、缺血组和梗死组。左心室容积曲线的收缩部分也使用指数衰减公式进行分析。使用该公式获得的闪烁扫描参数称为射血常数（Ec）。结果：梗死组、缺血组和正常组的Ec结果分别为1.8±0.8、2.7±0.9、3.5±1，Ec结果两组间差异有统计学意义（p≤0.001）。结论：Ec可能作为评价左心室收缩功能的闪烁扫描参数在临床上发挥作用。
