摘要
目的 :评价二硝酸异山梨酯 (Isoket)介入 99m Tc-甲氧基异丁基异腈 (MIBI)心肌断层显像检测心肌梗死后存活心肌的价值 ,并观察 99m Tc- MIBI心肌显像评价急性心肌梗死 (AMI)与陈旧性心肌梗死 (OMI)存活心肌的差异。方法 :对 16例 OMI患者和 12例 AMI患者 ,分别进行静息 99m Tc- MIBI显像和 Isoket静脉介入后 99m Tc-MIBI心肌断层显像。结果 :静息 99m Tc- MIBI显像出现灌注异常 185个节段 ,根据心肌放射性分布情况打分 ,平均得分为 15 .1± 3.8,Isoket介入 99m Tc- MIBI显像后出现灌注异常节段为 16 0个 ,平均得分为 10 .8± 1.6 ,两者比较差别有显著性 (P<0 .0 1)。静息 99m Tc- MIBI显像出现的 185个灌注异常的节段中 16例 OMI占 10 2个 ,12例AMI占 83个 ;Isoket介入后 87个得到不同程度改善的节段中 OMI占 40个 ,AMI占 47个 ,两者比较 ,P <0 .0 5。结论 :Isoket介入 99m Tc- MIBI显像与静息 99m Tc- MIBI显像比较可明显提高对存活心肌检测的灵敏度 ,并对AMI存活心肌的检出率要明显高于
Objective:To evaluate the difference between rest 99m Tc-MIBI imaging and Isoket infusion 99m Tc-MIBI imaging in detecting viable myocardium and compare the difference of viable myocardium between old myocardial infarction (OMI) and acute myocardial infaction (AMI) with 99m Tc-MIBI tomography.Method:16 patients with OMI and 12 patients with AMI underwent 99m Tc-MIBI rest、Isoket-infusion 99m Tc-MIBI imaging.Result:185 segments of rest imaging and 160 segments of Isoket-infusion imaging were identified abnomal the meanscores of abnomal segments were 15.1 ± 3.8 , 10.8 ± 1.6 respectively (P< 0.01 ).In 185 improved segments with 99m Tc-MIBI rest imaging:16 patients with OMI had 102 segments and 12 patients with AMI had 83 segments.In 87 improved segmengs with Iskoet-infusion 99m Tc-MIBI imaging,OMI had 40 segmants,AMI had 47 segments (P< 0.05 ).Conclusion:Isoket-infusion 99m Tc-MIBI myocardial imaging may improve sensitivity for detecting viable myocardium in myocardial infarction and the detection for AMI is superior for OMI.
