脑白质疏松症的CTMRI征象及临床特征

Study on the sign of CT and MRI and clinical characteristics of leukoaraiosis

目的探讨脑白质疏松症的CT、MRI征象及临床特征。方法对80例脑梗死合并脑白质疏松患者的临床资料进行回顾性分析。结果脑白质疏松症CT表现为两侧基本对称的密度减低改变,而MRI则表现为不规则、边缘模糊的斑片状及斑点状信号,T2WI呈稍高信号改变,T2 Flair高信号改变。腔隙性脑梗死患者的脑白质疏松症最严重。认知功能障碍越严重的患者脑白质疏松症越严重。结论脑白质疏松症有比较特征性的CT及MRI表现,认知功能障碍与脑白质疏松症程度成正比。

Objective To explore the sign of CT and MRI and the clinical characteristics of leukoaraiosis. Methods The clinical data of 80 patients with cerebral infarction and leukoaraiosis in our hospital from December 2011 to December 2012 were analyzed retrospectively. Results The CT performance of leukoaraiosis showed an decrease of both sides basic symmetric density,and MRI showed irregular,edge blur patchy and mottled signal,T2WI demonstrated a little high signal change,and T2 flair high signal change. Lacunar cerebral infarction patients with cerebral white matter had the most serious osteoporosis. The more severe brain white matter in cognitive dysfunction in patients,the more serious osteoporosis. Conclusion Leukoaraiosis shows typical appearance on CT and MR images. Cognitive dysfunction is proportional to the degree of leukoaraiosis.
