摘要
本文介绍了103例心肌梗塞患者^(201)Tl心肌灌注显像潘生丁试验的结果,并对55例同时进行平面及断层显像的资料进行了分析。在断层即刻和延迟显像中灌注异常阳性率分别为93％及80％。诊断LAD、RCA和LCX各支病变的灵敏度为93％、89％及73％。51例有灌注异常的患者中有40例(72％)显示填充现象,提示同时存在有缺血性病变。结果显示^(201)Tl心肌灌注显像潘生丁试验不仅有助于心肌梗塞的诊断和病变部位及范围的了解,还有助于预后的估测和治疗方案的确定。
Dipyridamole (DP) 201T1 myocardial perfusion imaging was performed in 103 patients with myocardial infarction. The SPECT 201T1 scans of 55 patients were analysed. 34 cases of them also underwent a coronary angiography. The results showed that the scintigram had a sensitivity of 93% for the detection of myocardial infarction. The size of the perfu-sion defect accurately reflected the extent of the infarcted and/or jeopardized myocardium and is hence of prognostic value.
