概括
血管风险因素,如高血压,与特定脑部区域的白质强度 (WMH) 有关. 虽然高血压显示出明显的WMH模式,但其他因素主要增加了整体WMH体积.
科学领域:
- 神经学 神经学
- 血管医学 血管医学
- 神经成像是一种神经成像.
背景情况:
- 白质超强度 (WMH) 在老年人中很常见,与血管风险因素有关.
- 高血压是已知的WMH风险因素,但不同风险因素之间的具体模式尚不清楚.
研究的目的:
- 调查特定的血管风险因素与社区居民的WMH位置之间的关联.
- 为了确定不同的血管风险因素是否表现出独特的WMH分布模式.
主要方法:
- 通过Meta VCI地图联盟,从16个基于人口的队列 (15,653个人) 汇集了数据.
- 使用线性混合模型,在50个白质区域和与6个血管风险因素相关的协会中量化WMH体积.
- 根据年龄,性别,研究地点和WMH总体体积进行调整的分析.
主要成果:
- 高血压,吸烟,糖尿病和血管疾病史与较高的总WMH体积有关.
- 高血压在10个特定的白质区域中显示出与WMH的显著关联.
- 吸烟,糖尿病和肥胖症在控制WMH总体体积后,在一个地区与WMH有关.
结论:
- 高血压显示出白质强度过高的特征模式.
- 其他血管风险因素与区域性WMH的关联似乎是由WMH体积的一般增加驱动的,而不是特定区域的影响.

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,...
