White matter changes on CT brain scan are associated with neurobehavioral dysfunction in children with symptomatic HIV disease. Child Neuropsychol. 1995;1:93-105Brouwers P, Van der Vlugt H, Moss H, Wolters P, Pizzo P. White matter changes on CT brain scan are associated with neurobehavioral ...
晚期病例,CT显示低密度病灶边界清楚、不强化,35%～50%的病例伴脑室扩大,脑沟增宽,脑回变平等脑萎缩改变。多发硬化可各期病灶并存,CT常同时发现低密度和等密度病灶,增强扫描有或无强化,以及脑萎缩等多种表现。若病灶累及小脑和脑干,因骨质伪影干扰,常难以显示病灶;加之因部分容积效应漏诊小病灶,使CT的诊断敏感性...
脑小血管病(small vessel disease,SVD)是影响大脑小动脉、微动脉、小静脉和毛细血管的疾病过程的总称。根据影像学表现,国际血管改变神经影像标准报告小组的标准将CSVD主要分为:近期皮质下小梗死(recent small subcortical infarct,RSSI)、推测为血管源性的腔隙、推测为血管源性的脑白质高信号(white matter ...
脑小血管病(small vessel disease,SVD)是影响大脑小动脉、微动脉、小静脉和毛细血管的疾病过程的总称。根据影像学表现,CSVD主要分为近期皮质下小梗死(recent small subcortical infarct,RSSI)、推测为血管源性的腔隙、推测为血管源性的脑白质高信号(white matter hyperintensity,WMH)、血管周围间隙(perivascular space,...
and neuro-Behçet disease (Fig. 20.3). In still younger patients, many genetic disorders, referred to as leukodystrophies, affect predominantly the white matter (Fig. 29.1). Abscesses often originate at the gray–white junction, but extend into the white matter (Fig. 18.8). All of the mo...
As age and Parkinson's disease (PD) both play a role in the degeneration of brain white matter, we aimed to investigate a possible interaction effect of age and disease presence on white matter integrity in patients with PD. We studied white matter hyperintensity volume, global fractional anisot...
Premature white matter disease 来自 国家科技图书文献中心 喜欢 0 阅读量: 36 作者:Geoffrey Liu,Wei Zhou,David C Christiani 摘要: Understanding the pathophysiology, imaging and correlative preterm outcome of white matter ischemic injury is important to improve neonatal clinical practices and to support ...
The first section will discuss imaging modalities used and their application in the diagnosis and study of metabolic disease. The second section will focus on some characteristic disorders in which abnormal white matter is visualized on neuroimaging. Although not meant to be an exhaustive summary, ...
