概括
系统性红斑狼 (SLE) 患有轻度认知障碍 (MCI) 的患者显示灰质体积,皮质厚度和碎形尺寸减少. 这些大脑变化可能会导致SLE妇女的认知能力下降.
科学领域:
- 神经成像是一种神经成像.
- 神经学 神经学
- 类风湿病学 类风湿病学
背景情况:
- 系统性红斑狼 (SLE) 是一种可以影响大脑的自身免疫性疾病.
- 轻度认知障碍 (MCI) 是SLE (wSLE) 妇女的常见并发症.
- 传统的MRI通常无法检测MCI的WSLE患者的大脑变化.
研究的目的:
- 通过使用先进的神经成像技术,研究患有MCI的WSLE患者微妙灰质 (GM) 形态变化.
- 为了比较WSLE与MCI,WSLE没有MCI和健康对照 (wHC) 之间的大脑形态.
主要方法:
- 采用了基于voxel的形态测量 (VBM) 和基于表面的形态测量 (SBM).
- 分析的灰色物质体积 (GMV),皮质厚度 (CT),碎形尺寸 (FD) 和旋转指数 (GI).

Alzheimer's Disease: Overview
1.6K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

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,...

Imaging Studies VII: Vascular Imaging
312
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...

Imaging Studies for Cardiovascular System IV: CMRI
313
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,...
