多排螺旋CT血管成像和彩色多普勒超声评估颈动脉粥样硬化斑块对比研究

Comparative Study on Evaluating Carotid Atherosclerotic Plaque Between Multi-slice Spiral CT Angiography and Color Doppler Ultrasonography

目的比较多排螺旋CT血管成像(multi-slice spiral CT angiography,MSCTA)和彩色多普勒血流显像(color Doppler flow imaging,CDFI)在评估颈动脉粥样硬化斑块中的价值。方法采用CDFI、MSCTA对150例患者进行颈动脉检查,对比两种检查手段对诊断颈动脉粥样硬化斑块及判断血管狭窄程度方面的优缺点。结果 MSCTA与CDFI对颈动脉斑块的检出率Kappa值一致性较高(к=0.925,P<0.05);但对于斑块性质和血管管腔狭窄度的诊断结果,两种方法比较差异无统计学意义(P>0.05)。结论 MSCTA与CDFI对显示颈动脉粥样硬化斑块一致性较好。

Objective To compare the values between multi-slice spiral CT angiography （MSCTA） and color Doppler flow imaging （CDFI） in evaluating carotid atherosclerotic plaque, Methods A total of 150 patients with carotid atherosclerosis plaque were examined carotid by using CDFI and MSCTA, and the advantages and disadvantages of two methods for diagnosing carotid atherosclerostic plaque and vessel stenosis were compared. Results There was a higher consistency in detection rate of carotid atherosclerotic plaque between MSCTA and CDFI（k= 0. 925, P〈0. 05）. But there was no significantly differences in the detection rate of plaque characteristics and atherosclerostic stenosis degree between two methods （P〉0. 05）. Conclusion MSCTA and CDFI have preferably consistency in detection of carotid atherosclerot- ic plaque.
