摘　　要：目的探讨CT与MRI对颈动脉狭窄和粥样硬化斑块特征的评估能力。方法回顾分析44例患者同期接受MRI与CT检查,对比两种检查方法诊断颈动脉狭窄和粥样硬化斑块的差异。结果 CT检查血管平均狭窄率29%,MRI检查3D TOF法血管平均狭窄率35%;黑血法血管平均狭窄率28%。MRI检查发现钙化45处,CT发现81处;CT检查显示的36处小点状钙化MRI未能显示。结论 CT与MRI均能判断病变血管的管腔狭窄程度;对颈动脉粥样硬化斑块钙化的显示,CT优于MR;综合多序列扫描影像特点,可以提高MR诊断准确率。Objective Investigate CT and MR1 in the assessment of carotid artery stenosis and atherosclerotic plaque characteristics. Methods Retrospective analysis of 44 patients under going MRI and CT exanfinations over the same period, compared to the two methods of diagnosis of carotid stenosis and atherosclerotic plaque difference in. Results The CT examination Vascular average stenosis rate of 29%, the average MRI check the 3D TOF vascular stenosis rate of 35%; the black blood Sequence vascular average stenosis rate of 28%. MRI exanfination revealed calcification in 45 CT found 81; 36 CT exmlfination showed small punctate calcification MRI failed to show. Conclusion CT and MRI can judge the degree of stenosis of the coronary arteries; carotid atherosclerotic plaque calcification display, CT is superior to the MR; comprehensive multiple sequence scanned image characteristics, MR diagnostic accuracy can be improved.
