摘　　要：目的：探讨双源CT冠状动脉造影在冠心病合并2型糖尿病患者中的应用价值.方法：选择内黄县第二人民医院心内科临床确诊冠心病合并2型糖尿病患者88例行双源CT冠状动脉造影检查,并同期行选择性冠状动脉造影.双源CT的原始数据均行曲面重组、容积再现、横断面重建及最大密度投影.结果：352支血管中（直径≥2mm）,双源CT冠状动脉造影显示≥50％狭窄的血管为163支,占46.3％选择性冠状动脉造影显示≥50％狭窄的血管为155支,占44％.与选择性冠状动脉造影对照分析,双源CT冠状动脉造影评价冠状动脉狭窄（≥50％狭窄）的特异性、敏感性、阳性预测值以及阴性预测值分别为89.9％、92.3％、87.7％和93.7％.结论：双源CT冠状动脉造影是检测冠心病合并2型糖尿病患者冠状动脉狭窄的较可靠的方法.OBJECTIVE： To investigate the value of dual source computed toinography angiography for diagnosis of the patients with coronary artery disease and type -2 diabetes mellitus. METHODS： Both dual source computed tomography angiography and coronary angiography were peflbrmed in 88 patients with coronary artery disease and type - 2 diabetes mellitus in the second hospital of Nei Huang. Volume rendering, multiplanar reconstruction, maximum density projection and transverse section reconstruction were performed. RESULTS： Of the 352 segments of coronary artery （diameter≥2mm） of 88 patients, 163 were detected to have stenosis≥ 50% （46. 3% ） by dual source spiral computed tomography angiography, 155 were detected to have stenosis ≥50% （44.0%） By coronary angiography. The sensitivity, specificity, positive predictive value and negative predictive value of 64 slice spiral computed tomography angiography for detecting stenosis≥50% were 92. 3%, 89.9%, 87.7% and 93.7% respectively. CONCLUSION ： This study suggests that dual source 64 slice spiral computed tomography angiography carl be used as a reliable diagnostic tool for detecting coronary artery, stenosis in patients with type -2 diabetes mellitus.
