脑动脉及分支粥样硬化狭窄MRA表现与分析

【摘要】 目的探讨脑动脉粥样硬化狭窄影像表现。方法采用脑动脉3D-TOF-MRA重建成像、颈部动脉3D-TOF-MRA增强重建成像技术,对612例动脉粥样硬化狭窄影像特征和狭窄程度进行评估,并与100例正常脑动脉对照组进行比较,血管变化有明显差异性。结果 612例脑动脉粥样硬化患者脑内血管有分支减少变细、血管欠光滑、呈小齿状、锯齿状、串珠状、局限性狭窄、节段性狭窄、闭塞等MRA表现;动脉粥样硬化狭窄程度有轻、中、重度和闭塞。结论动脉粥样硬化狭窄程度和范围与脑梗死程度和范围相一致。更多还原

【Abstract】 Objective To investigate the radiologic manifestation of cerebral atherosclerotic stenosis.Methods Use cerebral artery 3D-TOF-MRA reconstruction imaging,carotid artery enhanced 3D-TOF-MRA reconstruction imaging and TCD examination to evaluate the stenosis degree and radiologic characteristics of 612 patients who had atherosclerotic stenosis,and 100 control group whose brain arteries were normal for comparison,there were obvious differences in vascular changes.Results The MRA manifestations of 612 patients with cerebral atherosclerosis were:vessels branches reduced and been thinner,blood vessel owed to smooth,was small toothed,serration,bead-like,local stenosis,segmental stenosis and occlusion;the degree of atherosclerotic stenosis divided into mild,moderate,severe,and occlusion.Conclusion The degree and range of cerebral infarction was consistent with the degree and range of atherosclerosis stenosis.更多还原
