科学领域:
- 神经成像是一种神经成像.
- 脑血管健康 脑血管健康
- 淋巴系统功能 淋巴系统功能
背景情况:
- 淋巴系统从大脑中清除废物,其功能障碍与认知能力下降有关.
- 脑血管成像标记可能反映潜在的大脑健康,并影响淋巴功能.
研究的目的:
- 研究脑血管成像关键标志物与认知正常个体的淋巴功能之间的关联.
主要方法:
- 在574名认知正常参与者的回顾性分析中,使用了脑部MRI.
- 通过ALPS指数评估的淋巴功能 (沿周血管空间指数的扩散张力图像的分析).
- 脑血管标志物包括白质强度 (WMH) 负担,大脑微型血流 (CMBs) 和状体体积 (CPV) 被量化.
主要成果:

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

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,...
