易损斑块多层螺旋CT的诊断价值

目的:探讨16层螺旋CT(MSCT)诊断易损斑块的作用及临床意义.方法:不稳定型心绞痛40例,所有患者均行16MSCT冠状动脉检查,与选择性冠状动脉造影(CAG)检查比较,对易损斑块的数量、部位及病变程度进行分析.结果:CAG检出病变支数78支,16MSCT检出病变支数支73支.两者相比差别无统计学意义.以CAG为标准,MSCT的敏感度87.2 %,特异性87.5%,准确度93.6%.以CAG为标准,MSCT总的斑块检出率为79.1%;各分支远段的斑块检出率较低;RCA的斑块检出率低于LAD和LCX.结论:16MSCT能对易损斑块做出无创性评价.

The diagnosis value of 16-slice spiral CT in the diagnosis of coronary unstable plaquchn

Objective:To investigate the rebliability of 16-slice CT in the diagnosis of coronary unstable plaqu instability and clincal significance.Methods:40 Cases of unstable angina patients clinieally diagnosed were enrolled,firstly 16-slice spiral CT coronary angiography,and contrasted the accuracy of selective coronary angiography for unstable plaque volume,location and the degree.Result:CAG found 78-vessel lesions,while 16 MSCT detected 73 lesions.Detection rate was of no significant difference.Compared with CAG,the 16 MSCT sensitivity 87.2 %,specifity 87.5%, accurary 93.6%.For coronary angiography as the standard,MSCT detection rate 79.1% of the total laque,Distal branches had far lower rate,RCA had a 1 ower percentage deteetionrate of plaque than LAD and LCX.Conclusion:16 MSCT can made for 16 MSCT can made for non-invasive evaluation of coronary unstable plaqu.
