摘要 目的评价ECToolbox软件测量门控心肌显像左室射血分数(LVEF)的临床价值。方法31例患者接受静息态门控心肌显像,用ECToolbox软件测量LVEF,并与一周内门控心血池显像测量的结果比较。结果全部患者用ECToolbox软件测量值与心血池显像测量值的相关性为r=0.699(P<0.001);二者无统计学差别(P>0.05)。EDV<70ml组患者ECToolbox软件测量值与心血池显像测量值无相关性;前者高于后者(P<0.05)。EDV≥70ml组ECToolbox软件测量值与心血池显像测量值呈强相关(r=0.834,P<0.001);二者无统计学差别(P>0.05)。ECToolbox软件测量值对左室收缩功能是否正常的判断与门控心血池显像无差别(P>0.05)。结论用门控心肌显像ECToolbox软件测量LVEF与门控心血池显像比较相关性好且结果准确,但EDV<70ml时会高估测量值。
