概括

深髓静脉 (DMVs) 在多发性硬化症 (MS) 患者的可见性和连续性降低,与增加的神经退行相关. DMV成像可以帮助评估MS的严重程度.

科学领域:

神经学神经学
神经成像是一种神经成像.
血管生物学血管生物学

背景情况:

多发性硬化症 (MS) 是一种慢性中枢神经系统 (CNS) 自免疫性疾病.
血管异常越来越多地与MS的发病有关.
敏感度加权成像 (SWI) 允许直接可视化内静脉.

研究的目的:

调查深髓静脉 (DMVs) 与多发性硬化症患者的神经退行症之间的关联.
用SWI评估DMV,并将发现与神经成像神经退行症和临床残疾标记相关联.

主要方法:

前性横截面研究包括34名多发性硬化患者和30名健康对照 (HCs).
通过SWI评估的DMV计数和得分 (反映可见性和连续性).
在DMV指标,白质病变 (WML) 量,大脑缩和扩展残疾状况尺度 (EDSS) 之间的相关性分析.

主要成果:

与HC相比,MS患者的DMV数量显著降低,DMV得分更高.
较低的DMV计数和较高的DMV得分与增加的WML体积,大脑缩和更高的EDSS得分相关.
DMV计数与WML负相关,而DMV得分与WML和EDSS正相关.

结论:

在MS患者中,减少DMV可见性和连续性与更大的神经退行有关.
DMV成像指标 (计数和得分) 显示了评估多发性硬化症严重性的潜在生物标志物.
基于DMV的SWI评估可以提供有关MS进展和残疾的有价值的见解.

关键词:

多发性硬化症 (MS) 是一种疾病.深层髓静脉 (DMVs) 是一种深层髓静脉.磁共振成像 (MRI) 的使用.易感度加权成像 (SWI) 的使用.

Veins of Head and Neck

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
