概括
阴道动脉周脉脂肪组织 (PVAT) 的增加与先前的脑梗塞有关. 这一发现表明PVAT可能在缺血性中风发生中起作用.
科学领域:
- 心血管成像 - 心血管成像
- 神经学 神经学
- 放射学 放射学是一门学科.
背景情况:
- 围绕动脉的周周血管脂肪组织 (PVAT) 越来越多地被认为是其在动脉样硬化中的作用.
- 了解动脉PVAT与脑血管事件 (如先前脑梗塞) 之间的关系对于风险分层至关重要.
研究的目的:
- 调查动脉PVAT数量与先前脑梗塞的存在之间的关联.
- 为了确定PVAT的定量测量是否可以作为脑梗塞的预测指标.
主要方法:
- 139名患有中度至重度动脉狭窄症的患者接受了MRI,用于血管壁和大脑成像.
- 进行了动脉PVAT (面积,面积指数,体积指数) 的定量分析.
- 使用后勤回归模型来评估PVAT测量与先前脑梗塞之间的关联.
主要成果:
- 患有先前脑梗塞的患者与没有脑梗塞的患者相比, carotid 动脉 PVAT 的数量显著增加.
- 冠状动脉PVAT区域,区域指数和体积指数在单变量分析中都与先前的脑梗塞有显著的关联.
- 这些关联在调整临床因素和斑块特征后仍然具有统计学意义.
结论:
- 动脉PVAT的数量,特别是在易受损伤的斑块组件的存在下,与先前的脑梗塞独立相关.
- 冠状动脉PVAT可以作为一种潜在的成像生物标志物,用于预测缺血性中风风险.

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,...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

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...
