采用~(99m)Te—MIBI对16例正常人,59例冠心病人进行了潘生丁试验SPECT心肌血流灌注显像。结果证实:结合潘生丁试验可提高静息心肌灌注显像诊断冠心病的灵敏度及发现更多的心肌缺血节段;对可疑OMI的鉴别具有重要的价值。局限性心肌梗塞静息时可表现为缺血,潘生丁试验时可表现为散在“岛状”心肌血流灌注缺损灶。
16 cases of normal subjects and 59 cases of coronary heart disease were subjected to dipyridamole SPECT myocardial perfusion imaging with ~ (99m) Te-MIBI. The results show that: combined with dipyridamole test can improve the sensitivity of resting myocardial perfusion imaging diagnosis of coronary heart disease and found more myocardial ischemia segment; the identification of suspicious OMI has important value. Limitations myocardial infarction at rest can be manifested as ischemia, dipyridamole test can be manifested as scattered “island” myocardial perfusion defect lesions.
