摘要
目的:评价MSCT三维图像重组判断冠状动脉钙化与管腔狭窄程度的价值.方法:35例怀疑冠心病患者行冠状动脉MSCT检查,先行平扫进行钙化积分,再行增强扫描,并进行3D图像后处理包括曲面重组(CPR)及仿真内镜(VE)、最大密度投影(MIP)等方法分析病变节段的钙化程度、血管狭窄程度及其相关性.结果:11例共27支血管发现有钙化斑块导致管腔狭窄,可进行分析的23支血管管腔的狭窄程度10%~79%不等,与相应节段得到的钙化积分有一定的相关性.结论:MSCT曲面重建结合其它方法,对诊断冠状动脉狭窄程度有一定的价值.
Objective:To assess the value of multi-slice CT (MSCT) 3D reformation in the evaluation of coronary calcium score and stenosis of the coronary artery.Methods:MSCT was performed in 35 patients with coronary heart disease.Plain CT scanning was performed and calcium score was determined,then enhanced CT scanning was performed and 3D post-processing including multiplanar curved reformation,virtual endoscopy and maximum intensity projection were performed and degree of calcification,degree of vascular stenosis and their relationship were analyzed.Results:Calcium plaque with resulting stenosis of coronary artery was observed in 11 cases with 27 vessels.The degree of stenosis was 10%~79% in 23 of the 27 vessels and there was certain correlation between the stenosis and calcium score of corresponding segment of the vessels.Conclusion:MSCT curved planar reformation combined with other techniques of reformation has definite value for evaluation of degree of coronary artery stenosis.
