概括

2型糖尿病 (T2DM) 与大脑缩有关,特别是在海马和额叶. 先进的MRI可以检测这些神经退行变化,有助于糖尿病患者的早期诊断和监测.

科学领域:

神经成像是一种神经成像.
放射学放射学是一门学科.
内分泌学在内分泌学.

背景情况:

2型糖尿病 (T2DM) 与神经退行性变化有关,可以通过先进的磁共振成像 (MRI) 检测到.
在T2DM中,大脑缩与认知能力下降有关,但大脑的结构性变化尚未完全理解.
这项研究使用基于voxel的形态测量 (VBM) 调查了T2DM和没有T2DM个体之间大脑结构的体积差异.

研究的目的:

评估T2DM与非糖尿病患者之间大脑结构的体积差异.
探索T2DM中结构性大脑变化的模式和程度.
评估基于MRI的体积分析对检测T2DM相关神经退行症的有用性.

主要方法:

一项前性观察性研究,共86名参与者 (43名T2DM,43名对照).
获得了高分辨率的3DMRI扫描 (3D SPGR和T1加权的快速旋转回声).
使用SPM-12和CAT-12的基于voxel的形态测量 (VBM) 分析了24个大脑区域;统计分析包括独立的t测试和线性回归 (p <0.05).

主要成果:

在两种MRI序列中,T2DM受试者表现出显著的灰质体积减少,特别是在海马和中额头,在两种MRI序列中.
T1 FSE成像显示显著的双边海马缩,而3DSPGR数据没有.
这两种序列都表明T2DM参与者的前后叶体积显著增加,这表明过度缩小.

结论:

T2DM与认知相关区域的显著大脑缩有关.
基于MRI的体积分析可以早期检测和监测T2DM相关的神经退行.
建议在糖尿病人群中进行常规的神经成像;需要进行纵向研究以了解缩进展.

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...
