【摘要】 建立一种新的定量方法 -色标上限值上。将这种方法应用于冠心病和原发性高血压的心肌灌注像影分析中。结果 :显示对心肌缺血灵敏度的 81.8% ,特异性为 87.5 % ,35例原发性高血压病患者中 19例有一个或一个以上的室壁定量值R高于正常上限。且各壁的平均R值均高于对照组的平均R值。本文还对定量法、目测法及冠状动脉造影进行了比较 ,提示定量法保持了诊断的灵敏度 ,提高了诊断的特异性。降低了假阳性。定量法简单易行 ,克服了目测分析某些主观因素的影响。特别是对下壁及心尖压的诊断更准确 ,可作为目测分析的有益补充更多还原

【Abstract】 Objective:To retablish a quantitative method:the biggest volume of grayscale method (BVG).Methods:The myocardial perfusion imaging of 29 control subjects and 33 cases with coronary artery disease (CAD) and 35 cases with essential hypertension disease were analyzed by the quantitative method,the comparison of 24 cases operated by coronary angiography (CAG) were perfermed between BVG and CAG.Results:The sensitivity and specificity for CAD of the BVG were 81.8% and 87.5%,respectively.The R volumes of 19 cases essential hypertension disease were more than controls.Conclusions:the results of BVG are same as CAG,and BVG improves the rate of diagnosis for CAD.更多还原
