核素门控心血池显像与心肌断层显像在冠心病诊断中的对比

A Comparison of Diagnostic Value in Coronary Artery Disease with Gating Cardiac Blood-Pool Image and SPECT Myocardial Perfusion Image

笔者对１３４例冠心病患者的门控心血池显像（ＧＣＢＰ）与心肌断层显像结果进行了对比分析。结果显示：在心肌梗塞的诊断中，两种方法均有很高的灵敏度与特异度，单项检查均可达到诊断目的。ＧＣＢＰ显示室壁瘤较心肌断层更直观。在心肌缺血诊断中，心肌断层准确可靠，灵敏度为７９．２％，特异度为１００％。ＧＣＢＰ诊断心肌缺血只要掌握合适的标准其灵敏度与特异度与心肌断层相近，在检出病支血管方面心肌断层较ＧＣＢＰ更准确。

The authors compared and analysed between the gating cardiac blood-pool image(GCBP)and the SPECT myocardial perfusion image(SPECT)in 134 patients with CAD.The results showed that both methods had high sensitivity and specificity in diagnosis of myocardial infarction.Each of them can achieve diagnostic aim.The GCBP displaying ventricalar aneurysm was better than that of the SPECT.The SPFCT diagnosis in myocardial ischemia was reliable.The sensitivity and specificity was 79.2% and 100%,respectively.If a proper diagnostic standard was used,the GCBP in diagnosing myocardial ischemia will have the similar value as that of the SPFCT.In finding the lesions of coronary arteries,the SPECT is better than the GCBP imaging.
