| 摘 要： | 与冠脉造影对照,用多巴酚丁胺~(99m)锝-MIBI心肌断层显像(Dobu—ECT)预测62例心肌梗塞后患者冠脉病变的价值.对所有血管有明显狭窄病变者,82%可被Dobo—ECT检出病变血管区域心肌有缺损;对多支血管病变者,有84%可被检出有多支血管供血区域心肌缺损.检测重度血管狭窄的敏感性高于中等度血管狭窄(P<0.01).Dobu-ECT对检出右冠状动脉敏感性为94%,均高于前降支或回旋支,但特异性低于前降支或回旋支,仅为63%.结论:多巴酚丁胺~(99m)锝-MIBI心肌显像能够准确识别心肌梗塞后具体冠脉病变.

| Abstract: | Compared with coronary artery angiography, we evaluated dobufamine technetium-99m-MIBI SPECT (Dobu -ECT) in predicting individual vessel disease after myocardial infarction. Eighty -two percent of all significantly stenosed vessels were detected with Dobu-ECT,and 84% patients with multivessel disease could also be accurately identified. The sensitivity of Dobu-ECT was significantly greater for detecting severe stenosis than moderate one. The sensitivity for detecting stenosis in right coronary artery was better than left anterior descending or left circumflex, but its specificity was lower than the latter. Conclusion: Dobu-ECT can accurately detect significantly stenosed vessels. |
