摘要
目的:通过双源CT(DSCT)冠状动脉成像与冠状动脉造影(CAG)的对照研究,探讨DSCT评价冠状动脉狭窄及不同性质斑块的应用价值。方法:收集112例疑似冠心病患者的影像资料,对管腔直径≥1.5mm的冠状动脉节段进行分析,测量冠状动脉狭窄节段的程度及斑块的CT值。比较DSCT与CAG对冠状动脉狭窄程度及不同性质斑块导致的狭窄程度判断的一致性。结果:①DSCT对冠状动脉狭窄及节段狭窄程度的判断与CAG具有高度一致性。②对钙化斑块和混合斑块导致的冠状动脉狭窄的诊断,DSCT和CAG具有高度一致性,对非钙化斑块导致的冠状动脉狭窄的诊断具有中度一致性。2例因非钙化斑块冠状动脉狭窄<50%者,随访过程中发生急性冠脉综合征,发生率为1.8%。结论:DSCT冠状动脉成像能准确评价冠状动脉的狭窄程度,并辨别粥样硬化斑块的性质,是冠状动脉病变的首选检查方法。
Objective:The application value of double-source CT(DSCT)in the diagnosis of coronary artery sclerosis and the plaques was studied by using DSCT coronary angiography and selective coronary angiography.Methods:The imaging data of 112 patients suspected of coronary heart disease were collected,all the patients were examined for coronary angiography within three weeks.The images were analyzed with a lumen diameter greater than 1.5 mm.The degree of coronary artery stenosis and CT values of different patches were measured,the diagnosis results by DSCT and coronary angiography were compared.Results:The results suggested that the two kinds of inspection methods,DSCT and coronary angiography,had high consistency in diagnosis of the degree of coronary artery stenosis of each segments,the calcified plaques and the mixed plaques.The results also showed the two methods had moderate consistency in diagnosis of the non-calcified plaques.Conclusions:DSCT can accurately evaluate the narrow degree of coronary artery,can identify the compositions of atherosclerosis plaques.It is a kind of non-invasive and simple diagnosis of coronary artery disease of the first choice examination method.
