概括

遗传性转基因氨基粉症与多神经病变 (ATTRv-PN) 显示大脑早期白质损伤. 多模式MRI有效地检测到ATTRv-PN患者中这种中枢神经系统损伤.

科学领域:

神经学神经学
放射学放射学是一门学科.
遗传学是一个遗传学.

背景情况:

遗传性Transthyretin Amyloidosis与多神经病变 (ATTRv-PN) 是一种遗传性TTR基因突变疾病.
在ATTRv-PN中氨基酸沉积会影响周围神经,并显示出显著的中枢神经系统 (CNS) 参与.
在ATTRv-PN中早期发现中枢神经系统损伤至关重要,需要先进的神经成像.

研究的目的:

在症状和症状前的ATTRv-PN患者中调查大脑白质微结构损伤.
评估多模式MRI技术在检测ATTRv-PN中中枢神经系统变化的有用性.
评估症状和症状前ATTRv-PN个体之间的认知功能差异.

主要方法:

使用了全面的临床评估和多模式MRI (FreeSurfer,TBSS,微型血液分析).
包括30名有症状的ATTRv-PN患者,19名症状前 (ATTRv-PN前) 患者和44名对照.
使用阿登布鲁克认知检查-修订的认知评估认知.

主要成果:

ATTRv-PN患者表现出扩散的皮质下白质变化.
在大脑成像中,皮层稀疏和微型血液是罕见的发现.
与非症状患者相比,症状患者在记忆和口语流方面得分明显较低.

结论:

ATTRv-PN的特征是早期的大脑白质微观结构损伤.
多模式MRI是一种准确的,非侵入性的工具,用于检测ATTRv-PN.中枢神经系统损伤.
这些发现提高了对ATTRv-PN疾病谱和中枢神经系统参与的理解.

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...
