概括
髓寡腺细胞糖蛋白抗体相关疾病 (MOGAD) 显示的脑缩比复发性复发性多发性硬化症 (RRMS) 较少. MOGAD患者的大脑体积更大,并且随着时间的推移没有显著的T2病变进展.
科学领域:
- 神经免疫学 神经免疫学
- 神经学 神经学
- 放射学 放射学是一门学科.
背景情况:
- 髓寡细胞糖蛋白抗体相关疾病 (MOGAD) 对大脑缩的影响在很大程度上是未知的.
- 大脑MRI体积和T2损伤负担是神经退行症的关键指标.
研究的目的:
- 为了比较MOGAD患者的大脑MRI体积和T2病变体积,与复发性复发性多发性硬化症 (RRMS) 患者和健康对照 (HC) 患者进行比较.
- 为了研究MOGAD中的纵向大脑体积变化.
主要方法:
- 一项多中心纵向研究,比较了16名成年MOGAD患者,44名RRMS患者和14名HC患者.
- 对脑部MRI扫描的分析,包括全球大脑,白质 (WM),灰质 (GM) 和T2损伤体积,在18 ± 6个月的时间内.
- 年度百分比大脑体积变化 (PBVC/y) 的计算.
主要成果:
- 与RRMS患者相比,MOGAD患者表现出较低的PBVC/y (p=0.014).
- MOGAD患者的平均全球大脑 (p=0.012) 和WM体积 (p=0.024) 较高,但基线时T2损伤体积中位数较低 (p<0.001).
- 在RRMS (p<0.001) 中,T2损伤体积随着时间的推移而增加,但在MOGAD (p=0.262) 中没有增加.
结论:
- 与RRMS相比,MOGAD结构性大脑MRI特征包括更高的全球大脑和WM体积.
- 与RRMS相比,MOGAD表明随着时间的推移减少了大脑体积损失.
- 这些发现表明,MOGAD和RRMS背后存在着不同的致病基因机制.

Magnetic Resonance Imaging
7.6K
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,...
