Aphasia after stroke is one of the common complications of cerebral infarction. Early diagnosis and treatment of aphasia after stroke is of great significance for the recovery of language function. At present, there are different views on the pathogenesis of aphasia after stroke. Functional magnetic resonance imaging (fMRI) can reflect the brain function, brain tissue metabolism, and the level of brain local blood flow. It has the advantages of noninvasive, high resolution and sensitivity, low price, and so on. It has been widely used in the study of sensory aphasia after stroke. This study focuses on the development of functional magnetic resonance imaging in patients with poststroke aphasia and summarizes the published studies on functional magnetic resonance imaging in patients with poststroke aphasia. : A literature search was conducted in PubMed, Hindawi, PLoS, IEEE, Wiley, ScienceDirect, Springer, EMBASE, and web of science, with the keywords of "stroke" and "Aphasia" and "functional magnetic resonance imaging", "RS fMRI", or "DTI", to review the research of functional magnetic resonance imaging in patients with aphasia after stroke. The results included clinical evaluation, diagnostic scale, and imaging analysis; the study design was a randomized controlled trial, case series and case report, and observational study. A total of 67 articles were identified in the first search and 43 after the second search. Based on the analysis of 43 selected articles, 19 articles were included, and 24 articles were excluded. The selected information is shown in Table 1. Eleven of them did not contain imaging-related data. Six articles are related review articles. Four studies were conducted on patients without poststroke aphasia. Three studies studied the effect of poststroke aphasia on patients' social participation.
脑梗死后失语症是脑梗死常见的并发症之一。早期诊断和治疗脑梗死后失语症对语言功能的恢复具有重要意义。目前，对脑梗死后失语症的发病机制有不同的看法。功能磁共振成像（fMRI）可以反映脑功能、脑组织代谢和局部脑血流水平。它具有无创、高分辨率和灵敏度、价格低廉等优点，已广泛应用于脑梗死后感觉性失语症的研究。本研究重点关注功能磁共振成像在脑梗死后失语症患者中的发展，并总结了发表的关于脑梗死后失语症患者功能磁共振成像的研究。方法：在 PubMed、Hindawi、PLoS、IEEE、Wiley、ScienceDirect、Springer、EMBASE 和 web of science 上进行文献检索，关键词为“stroke”和“Aphasia”以及“functional magnetic resonance imaging”、“RS fMRI”或“DTI”，以回顾功能磁共振成像在脑梗死后失语症患者中的研究。结果包括临床评估、诊断量表和影像学分析；研究设计为随机对照试验、病例系列和病例报告以及观察性研究。第一次搜索共确定了 67 篇文章，第二次搜索后确定了 43 篇文章。基于对 43 篇选定文章的分析，共纳入 19 篇文章，排除 24 篇文章。所选信息见表 1。其中 11 篇文章未包含与影像学相关的数据。6 篇文章是相关的综述文章。4 项研究针对的是没有脑梗死后失语症的患者。6 项研究研究了脑梗死后失语症对患者社会参与的影响。
