摘　　要：本文探讨冠状动脉CT血管成像(CCTA)冠状动脉周围脂肪衰减指数(FAI)联合上胸部补充扫描与图像大视野重建在冠心病筛查中的应用价值。选取80例可疑冠心病患者,均接受CCTA及CAG检查。经CAG确诊,其中冠心病患者56例,非冠心病患者24例。冠心病组FAI值明显低于非冠心病组(P<0.05)。冠心病组重度狭窄FAI值明显低于轻度和中度狭窄(P<0.05)。FAI值与狭窄程度呈负相关(r=-0.511,P<0.05)。FAI值预测诊断冠心病的ROC曲线下面积为0.947(P<0.05)。大视野重建后发现心外病灶患者46例,行胸部补充扫描后,另发现心外病灶患者12例,共计发现73处病灶。CCTA冠周FAI在诊断冠心病中有较好的价值,同时结合上胸部补充扫描与图像大视野重建,有助于发现心外病灶。This paper discussed the value of coronary CT angiography(CCTA)in screening coronary heart disease with peripheral fat attenuation index(FAI)combined with upper chest supplementary scanning and image wide field reconstruction.80 patients with suspected coronary heart disease were selected to receive CCTA and coronary angiography(CAG).After CAG,there were 56 patients with coronary heart disease and 24 patients without coronary heart disease.The FAI value of the coronary heart disease group was significantly lower than that of the non coronary heart disease group(P<0.05).The FAI value of severe stenosis in CHD group was significantly lower than that of mild and moderate stenosis(P<0.05).FAI was negatively correlated with the degree of stenosis(r=-0.511,P<0.05).The area under ROC curve of coronary heart disease predicted by FAI was 0.947(P<0.05).Forty-six patients with extracardiac lesions were found after wide field reconstruction,and 12 patients with extracardiac lesions were found after supplementary chest scanning,a total of 73 lesions were found.CCTA coronal FAI has good value in the diagnosis of coronary heart disease.At the same time,combined with supplementary upper chest scanning and image large field reconstruction,it is helpful to find the extracardiac lesions.
