目的:分析对比多排螺旋CT与MR对颈动脉狭窄和粥样硬化斑块特征进行评估。方法:选取我院2011年5月至2014年5月间收治的缺血性脑血管疾病患者280例,分别接受多排螺旋CT和MR检查,记为CT组和MR组,分别为140例。待检查完患者之后,观察颈动脉狭窄程度以及粥样硬化斑块的相关情况。对比两种检查方法在判断血管狭窄程度方面的优劣。结果:CT组患者经多排螺旋CT检查血管的平均狭窄率达到30%,80处出现钙化,无法显示斑块内出血;而MR组患者经过MR检查血管平均狭窄率达到29%,40处出现钙化,显示斑块内有小灶出血。多排螺旋CT和MR对于诊断血管狭窄程度无差异性P>0.05。结论:多排螺旋CT与MR都可以较好的判断病变血管狭窄程度,但MR较适合于分析颈动脉粥样硬化斑块特征。
OBJECTIVE: To analyze the characteristics of carotid artery stenosis and atherosclerotic plaque by comparing multislice CT and MR imaging. Methods: A total of 280 patients with ischemic cerebrovascular disease who were admitted to our hospital from May 2011 to May 2014 were enrolled in this study. They were examined by multislice spiral CT and MR imaging respectively, which were recorded as CT group and MR group respectively, 140 cases. After examining the patient, observe the degree of carotid stenosis and related atherosclerotic plaques. Comparison of two methods of inspection in determining the extent of vascular stenosis of the pros and cons. Results: In the CT group, the mean vessel stenosis rate was 30% in multi-slice spiral CT, calcification was found in 80, and plaque hemorrhage was not detected. In MR group, the mean vessel stenosis rate was 29% and 40 , Showing plaque within a small hemorrhage. Multi-slice spiral CT and MR had no difference in diagnosis of vascular stenosis (P> 0.05). Conclusion: Multi-slice spiral CT and MR can be a good judge of the degree of vascular stenosis, but MR is more suitable for the analysis of carotid atherosclerotic plaque characteristics.
