|November 28, 2024
概括
住院治疗COVID-19与海马体积减少和认知功能低下有关,即使没有显著的白质变化. 这些大脑变化可能表明住院患者最近的病变和缩.
科学领域:
- 神经学 神经学
- 传染性疾病 传染性疾病
- 放射学 放射学是一门学科.
背景情况:
- COVID-19 (冠状病毒疾病2019) 可以影响大脑健康,通过临床MRI观察到的神经表现.
- 像7特斯拉 (7T) MRI这样的先进成像,与3特斯拉 (3T) MRI相比,提供更高的分辨率来检测微妙的脑损伤.
研究的目的:
- 为了比较需要住院治疗的COVID-19患者和未住院治疗的患者之间的白质超强度 (WMH),海马子子子体积和认知功能.
- 在这些群体中调查脑成像发现和认知表现之间的潜在相关性.
主要方法:
- 一项涉及179名参与者 (52人因COVID-19住院,111人未住院) 的多站点研究,他们接受了7TMRI扫描和全面的认知评估.
- 分析包括WMH和海马体子场体积测量,对内体积进行校正,以及统计比较 (皮尔森相关性,未配对的t测试).
主要成果:
- 在住院和非住院组之间没有发现WMH体积的显著差异.
- 住院COVID-19患者的海马体积显著减少 (p=0.0497) 和认知得分降低,特别是在记忆和执行功能测试中 (例如,MoCA,Trail Making Test B,Craft Recall).
结论:
- 与非住院患者相比,COVID-19的住院治疗与海马体积减少和认知能力受损有关.
- 这些发现表明,住院患者的WMH和海马体积减少可能与更差的认知结果相关,可能反映了最近的脑损伤或缩.

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
