【摘要】 目的 比较核素心肌SPECT显像与电子束CT(EBCT)扫描对冠心病(CHD)的诊断价值。方法 对64例受检者(CHD患者50例,非CHD患者14例)进行了冠状动脉造影、SPECT及EBCT检查。结果 以冠状动脉造影为金标准,SPECT与EBCT诊断CHD的灵敏度相近,分别为92.0%和94.0%;SPECT的特异性(92.9%)优于EBCT(28.6%),P<0.05。在判断EBCT结果时,采用不同的钙化积分阈值,对诊断CHD的灵敏度和特异性影响很大,故应采用接收器工作特性分析确定适当的钙化积分阈值。结论 EBCT虽具有一定优越性,但目前尚不能取代心肌SPECT显像。

    【Abstract】 Purpose Tocomparatively study ^99m Tc-MIBI SPECTand electron beam CT (EBCT) in diagnosing coronary heart disease (CHD). Methods 64 patients (54 men, 10 women; mean age 59.7years) underwent SPECT,EBCT and cononary arteriography within one month. Results Using coronary arteriographic findings as gold standard, thesensitivities of SPECT and EBCT for diagnosing CHD were 92.0% and 94.0%, the specificitieswere 92.9% and 28.6%, respectively. The sensitivity and specificity of EBCT for diagnosingCHD were varying with different threshold limits used for coronary calcification scoring.Receiver operating characteristic analysis should be used to define the appropriatethreshold limit for coronary calcification scoring. Conclusions EBCT is of some advantages, but should not be used in place ofSPECT in diagnosis of CHD.
