概括
基本震 (ET) 患者,有或没有休息震,表现出类似的体 (CC) 异常. 这表明,在这种常见的运动障碍中,有共同的潜在大脑机制.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 放射学 放射学是一门学科.
背景情况:
- 基本震 (ET) 是一种普遍的运动障碍.
- ET可以呈现出静止 (ET-plus亚型).
- 在ET中注意到体 (CC) 的参与,但ET亚型之间的差异尚未研究.
研究的目的:
- 调查ET患者与没有静止震 (ETrt) 之间的CC结构差异.
- 将ET和ETrt患者的CC结构与健康对照 (HC) 进行比较.
- 通过使用多模式MRI探索潜在的共享病理生理机制.
主要方法:
- 128名参与者 (63人ET,38人ETrt,27人HC) 接受了多模式MRI.
- 对厚度,平均扩散率 (MD) 和分数异构性 (FA) 进行评估的CC genu,body和splenium.
- 利用组对比和无监督的集群分析.
主要成果:
- 与HC相比,ET和ETrt组都显示了CC厚度的减少和体内MD的增加.
- 在ET和ETrt组之间没有发现显著的结构差异.

Magnetic 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...

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,...

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,...
