概括

超磁刺激诱导的运动唤起潜能 (TMS-MEPs) 和[18F]FDG-PET扫描显示,在肌缩侧硬化症 (ALS) 中,上部运动神经元 (UMN) 损伤. 异常的TMS-MEPs与大脑新陈代谢的改变相关,有助于UMN评估.

科学领域:

神经科学是一个神经科学.
神经学神经学
医疗成像医学成像

背景情况:

肌缩侧面硬化症 (ALS) 诊断依赖于临床评估和低运动神经元损伤的电肌图.
在ALS中检测上部运动神经元 (UMN) 的参与仍然具有挑战性.
正在研究它们在评估UMN负担方面的作用.

研究的目的:

评估TMS-MEP在确定ALS患者神经生理UMN损伤方面的有效性.
探索TMS-MEP发现与[18F]FDG-PET测量的神经功能障碍之间的相关性.

主要方法:

对13名接受TMS-MEP和[18F]FDG-PET扫描的ALS患者的回顾性分析.
欧洲议会议员的评估包括正常,缺席或增加的中央电机导电时间.
[18F]FDG-PET扫描经过了对VOXEL的分析,将ALS患者与健康对照 (HC) 进行比较.

主要成果:

四名患者 (NO组) 的MEP正常,而九名患者 (AB组) 的MEP异常.
组AB在前中心,补充运动区域,偏中心叶片和前带皮层中表现出低代谢.
与HC相比,AB组也在右小脑和部区域表现出相对高代谢;NO组没有.

结论:

改变的大脑代谢仅在患有异常TMS-MEPs的ALS患者中观察到.
这些发现表明TMS-MEPs和大脑新陈代谢之间的联系在定义ALS的UMN损伤中.

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
