潘生丁负荷^(99m)Tc-MIBI心肌断层显像对冠心病心肌缺血的诊断价值

The value of dipyridamole stress^(99m)Tc-MIBI myocardial SPECT for detecting coronary artery disease

目的 评价潘生丁负荷 99m Tc- MIBI心肌断层显像用于冠心病心肌缺血诊断的可行性和临床价值。方法 静脉注入潘生丁 0 .14 mg· kg- 1 · min- 1 ,共 4 min,1min后注射 99m Tc- MIBI 74 0 MBq,1h后行心肌断层显像。结果 潘生丁负荷心肌断层显像诊断冠心病心肌缺血的灵敏度为 92 .5 % ,特异性为 92 .1%。潘生丁注入后引起的副作用轻微且较短暂。结论 潘生丁负荷 99m Tc-

Objective To evaluate the diagnostic value of dipyridamole stress 99m Tc MIBI myocardial SPECT for detecting coronary artery disease.Methods 99m Tc MIBI was injected one minute after administration of dipyridamole(0.14 mg·kg -1 ·min -1 ,4 min).Myocardial SPECT was performed at 1 hour after injection of 99m Tc MIBI.Results The sensitivity and specificity of dipyidamole stress 99m Tc MIBI myocardial SPECT for detecting coronary artery disease were 92.5% and 92.1%,respectively.The side effects were mild and temporary.Conclusion Dipyridamole stress 99m Tc MIBI myocardial SPECT is feasible for detecting coronary disease.
