背景情况:
- 消失白质 (VWM) 和元染色性白血病 (MLD) 是不同的白血病,影响不同病理的白质.
- 通过先进的成像来了解这些差异对于诊断和监测至关重要.
研究的目的:
- 评估定量核磁共振能否识别VWM和MLD之间的神经病理差异.
- 为了确定定量MRI发现是否与这些条件下的临床得分相关.
主要方法:
- 未来包括VWM,MLD患者和对照组 (2020-2023年).
- 使用3TMRI与多隔间放松计扩散信息化髓水成像 (MCR-DIMWI) 和多回声T2放松成像与压缩传感 (METRICS) 用于髓水分 (MWF).
- 采用多扩散加权成像用于扩散张力成像 (DTI) 和神经质定向分散和密度成像 (NODDI),以估计神经质密度指数,方向分散指数和自由水分数.
主要成果:

01:24Magnetic Resonance Imaging
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...
01:19Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
