The purpose of this article is to discuss classic applications in diffusion-weighted imaging (DWI) in demyelinating disease and progression of DWI in the near future.
DWI is an advanced technique used in the follow-up of demyelinating disease patients, focusing on the diagnosis of a new lesion before contrast enhancement. With technical advances, diffusion-tensor imaging; new postprocessing techniques, such as tract-based spatial statistics; new ways of calculating diffusion, such as kurtosis; and new applications for DWI and its spectrum are about to arise.
本文旨在讨论弥散加权成像（DWI）在脱髓鞘疾病中的经典应用以及 DWI 在近期的进展。
DWI 是一种应用于脱髓鞘疾病患者随访的先进技术，其重点在于在增强前诊断新病变。随着技术的进步，弥散张量成像；新的后处理技术，如基于束的空间统计学；新的扩散计算方法，如峰度；以及 DWI 及其谱的新应用即将出现。
