卒中后认知障碍(PSCI)是脑卒中后常见且致残性极高的并发症,目前临床诊断主要依赖神经心理学量表评估,但结果易受患者年龄、受教育程度及情绪状态等因素干扰。磁共振扩散成像(dMRI)技术可以无创性评估脑组织微结构改变,为深入研究PSCI提供了重要工具。本文就扩散张量微成像、扩散峰度成像、自由水扩散张量成像及神经突方向离散度和密度成像等技术在PSCI中的研究进展进行综述。
Post-stroke cognitive impairment (PSCI) is a common and highly disabling complication after stroke.Currently, clinical diagnosis primarily relies on neuropsychological scales for assessment, but the results are susceptible to confounding factors such as age, educational level,and emotional state.Diffusion magnetic resonance imaging (dMRI) techniques can non-invasively assess the microstructure changes of brain tissue, providing an important tool for in-depth research on PSCI.This article reviews the research progress of techniques such as diffusion tensor imaging,diffusion kurtosis imaging,free-water diffusion tensor imaging,and neurite orientation dispersion and density imaging in PSCI.
