- The normal limit of resting LVEF values was evaluated. Results The correlation between rest QGSPECT and rest gated blood pool imaging was: r =0 90 for LVEF( P <0 01), 0 94 for EDV ( P <0 01) and 0 97 for ESV( P <0 01). 结果 QGSPECT测量 3 5例不同左室功能受试者的静息左室功能参数LVEF(r =0 90 )、EDV(r =0 94)、ESV(r =0 97)分别与静息门控心血池显像计算的结果呈显著正相关 (P <0 0 1)。
