目的探讨双嘧达莫负荷心肌201T1单光子发射计算机断层摄影(SPECT)与运动负荷心肌99Tcm-甲氧基异丁基异腈(MIBI)SPECT显像在辅助诊断心脏x综合征中的价值.方法选取临床符合心脏X综合征诊断标准患者共63例,将患者分为2组,一组行双嘧达莫负荷心肌201T1 SPECT显像,另一组行运动负荷心肌99Tcm-MIBI SPECT显像,评价两种核素心肌显像在诊断心脏X综合征中的符合率.结果行双嘧达莫负荷心肌201T1 SPECT显像者35例,有31例出现病变部位的反向再分布,符合率为89%;行运动负荷心肌99Tcm-MIBI SPECT显像者28例,其中有24例出现负荷病变部位放射性稀疏或缺损,静息显像正常,符合率为87%.两种核素心肌灌注显像的符合率差异无统计学意义(P>0.05).结论双嘧达莫负荷心肌201T1 SPECT显像能较直接反映心脏x综合征冠状动脉微循环病变.

Objective To compare the value of dipyridamole 201T1 Single photon emission computed tomography (SPECT) myocardial imaging and exercise myocardial 99Tcm-MIBI SPECT imaging on diagnosing cardiac syndrome X.Methods Sixty-three patients with known cardiac syndrome X were divided into dipyridamole 201T1 SPECT myocardial imaging group (group 1,n = 35) and exercise myocardial 99Tcm-MIBI-SPECT imaging group (group 2,n = 28) and the diagnostic accuracy rates were compared.Results Thirty-one out of 35 cardiac syndrome X patients showed reverse redistribution in group 1 and the diagnostic accuracy rate was 89%.Positive test results were evidenced 24 out of 28 cardiac syndrome X patients in group 2 and the diagnostic accuracy rate was 87% (P > 0.05 vs.group 1).Conclusion The diagnostic accuracy rates of these two myocardial imaging methods were satisfactory and comparable on detecting cardiac syndrome X.
