用~(99m)Tc-异腈类心肌灌注显像剂对97例透壁性心肌梗塞和10例非透壁性心肌梗塞行心肌断层显像并与心电图对照,结果表明:心肌断层显像对透壁性心肌梗塞定位诊断的检出段数高于心电图,前者167个,后者143个.透壁性心肌梗塞97例心肌断层显像显示放射性缺损区84例,放射性稀疏区13例;非透壁性心肌梗塞10例,显示放射性稀疏区5例,可疑稀疏区4例,正常1例。以放射性缺损区存在为诊断标准,透壁性心肌梗塞检出率为86.6%,非透壁性心肌梗塞检出率为0。
Ninety-seven cases of transmyocardial infarction and 10 cases of non-transmyocardial infarction underwent myocardial perfusion imaging with ~ (99m) Tc-isonitrile myocardial perfusion imaging agent and compared with electrocardiogram. The results showed that: The number of detective segments of transmural myocardial infarction was higher than that of electrocardiogram, the former was 167 and the latter was 143. 97 cases of transmyocardial infarction with myocardial infarction showed 84 cases of radioactive defect, radioactive sparse area of 13 cases; Myocardial infarction in 10 cases, showing 5 cases of radioactive sparse area, 4 cases of suspected sparse area, normal in 1 case. To radioactive defect area as the diagnostic criteria, transmural myocardial infarction was detected 86.6%, non-transmural myocardial infarction was detected 0
