这是一项前性研究,涉及19名神经性WD患者,10名肝脏WD患者和25名健康对照.
使用3T磁力共振与DTI和FWI序列.
雇佣了基于voxel-wise路径的空间统计和兴趣地区分析.

主要成果:

神经性WD显示DTI (较低的FA,较高的MD/AD/RD) 具有广泛的白质变化.
FWI显示了更有限的领域的变化,表明了更高的特异性.
FWI指标与WD患者的临床严重性得分有显著的相关性.

结论:

与传统的DTI相比,FWI提供了对WD微结构变化的更精确的评估.
FWI指标显示了与WD临床严重程度的相关性和监测的潜力.

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...
