概括
半圆中心 (CSO) 中周血管空间 (PVS) 的增加与患轻度认知障碍 (MCI) 的风险更高有关. 这一发现表明,PVS严重程度可能表明早期认知能力下降.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 老年学是一门学科.
背景情况:
- 在MRI上可见的周血管空间 (PVS) 与痴呆症风险有关.
- PVS与早期认知障碍 (例如轻度认知障碍 (MCI)) 之间的联系尚未得到充分证实.
研究的目的:
- 调查MRI可见PVS与发生MCI的风险之间的关联.
- 分析与MCI风险相关的特定大脑区域 (基底和半圆中心) 的PVS严重程度.
主要方法:
- 利用了基于社区的弗雷明翰心脏研究 (FHS) 的数据.
- 包括50岁以上的参与者,在基线没有中风,认知障碍和痴呆症.
- 评估PVS严重程度,使用基底和半圆中心 (CSO) 的既定标准.
- 采用了考克斯回归分析,调整了人口和心血管因素.
主要成果:
- 总共有1,314名参与者被分析,其中263例MCI病例发生在7.4年的中位数随访期间.
- 在CSO中,较高的PVS严重程度与发生MCI的风险增加显著相关 (HR=2.55).
- 在CSO中PVS严重程度与MCI风险之间的关联在女性中显得更强烈.
- 在基底质中的PVS严重程度和MCI风险之间观察到名义上的,但没有统计学意义的关联.
结论:
- 半圆中心 (CSO) 的周周血管空间负担可能作为早期认知障碍的风险标志物.
- 需要进一步的研究来探索这种关联中性别特异性的差异.

Magnetic Resonance Imaging
5.2K
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...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
