概括

定量核磁共振测量显示,前臂肌肉变化发生在1型肌肉性缩症 (DM1) 中. 这些发现与肌肉强度,功能和肌相关,为监测疾病进展和治疗疗效提供了潜力.

科学领域:

神经学神经学
肌肉骨成像系统的成像

背景情况:

肌肉性缩症1型 (DM1) 是最常见的成年肌肉缩症,导致软弱和功能衰退.
在DM1中,定量MRI (脂肪分数,T2放松时间) 和上肢临床发现之间的关系尚不清楚.

研究的目的:

在DM1患者中使用定量MRI评估前臂肌肉结构.
为了将MRI测量与肌肉强度,功能和手握肌相关联.

主要方法:

18名成人DM1患者使用三点迪克森和T2旋回回声技术进行了前臂MRI.

主要成果:

在 flexor digitorum profundus 中观察到较高的脂肪分数和T2放松时间.
定量MRI值与强度 (r = -0.61至 -0.92),功能 (r = -0.64至 -0.83) 和手握肌 (r = 0.48) 有显著的相关性.
前臂前部脂肪分数与强度和功能的相关性比前臂后部脂肪分数更强.

结论:

定量核磁共振测量有效评估前臂肌肉病理在DM1.
这些MRI技术对监测DM1患者的治疗疗效有前途.

Magnetic Resonance Imaging

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...
