概括
不成比例地扩大了下大脑腔脑症 (DESH) 的严重程度与正常压力脑症 (NPH) 患者的白质变化相关. 这些发现表明DESH是NPH进展和症状严重性的潜在生物标志物.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 神经成像是一种神经成像.
背景情况:
- 正常压力脑症 (NPH) 的特点是白质完整性的改变,可以通过扩散张力成像 (DTI) 检测到.
- 不成比例地扩大的甲状腺下部空间头 (DESH) 已被提议作为NPH的预后指标.
研究的目的:
- 调查正常压力脑症 (NPH) 患者的扩散张力成像 (DTI) 指数,根据不成比例扩大的脑下空间脑症 (DESH) 的严重程度和临床症状分层.
- 探索DESH严重程度,DTI衍生的微观结构变化和NPH的神经症状严重程度之间的关系.
主要方法:
- 一项追溯病例控制研究,涉及33名NPH患者和33名匹配对照.
- 将NPH患者分为高DESH和低DESH分组,根据平均DESH尺度值进行分类.
- 在14个感兴趣的区域 (ROI) 中,在组之间比较DTI指数 (分数异构,轴向扩散率,平均扩散率,辐射扩散率).
主要成果:
- 高DESH组在侧面的冠状辐射中表现出增加的轴向扩散性.
- 在高DESH组中,在前面和侧面的冠状辐射和周周结膜白质中观察到分数异构性降低和平均和辐射扩散率增加.
- 具有较高临床症状评分的NPH患者在周围心室前角周围的周周心室白质中显著减少了分数异性质.
结论:
- 不成比例地扩大了下椎间盘脑症 (DESH) 的严重程度与DTI检测到的特定白质微观结构变化有关.
- DESH可以作为一种有价值的生物标志物,用于识别DTI检测到的微结构变化,并预测正常压力头症 (NPH) 中的临床症状严重程度.

Cranial and Spinal Meninges
1.5K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Spinal Cord: Cross-sectional Anatomy
1.9K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
