Wearing a face mask has become essential to contain the spread of COVID-19 and has become mandatory when collecting fMRI data at most research institutions. Here, we investigate the effects of wearing a surgical mask on fMRI data in n = 37 healthy participants. Activations during finger tapping, emotional face matching, working memory tasks, and rest were examined. Preliminary fMRI analyses show that despite the different mask states, resting-state signals and task activations were relatively similar. Resting-state functional connectivity showed negligible attenuation patterns in mask-on compared with mask-off. Task-based ROI analysis also demonstrated no significant difference between the two mask states under each contrast investigated. Notwithstanding the overall insignificant effects, these results indicate that wearing a face mask during fMRI has little to no significant effect on resting-state and task activations.
佩戴口罩已成为控制 COVID-19 传播的必要手段，在大多数研究机构采集 fMRI 数据时也已强制要求佩戴口罩。在此，我们调查了 n = 37 名健康参与者佩戴手术口罩对 fMRI 数据的影响。研究中检查了手指敲击、情绪面孔匹配、工作记忆任务和休息时的激活情况。初步 fMRI 分析表明，尽管口罩状态不同，但静息态信号和任务激活相对相似。与脱口罩相比，戴口罩时静息态功能连接的衰减模式可忽略不计。基于任务的 ROI 分析也表明，在所研究的每种对比下，两种口罩状态之间没有显著差异。尽管总体上没有显著影响，但这些结果表明，在 fMRI 过程中佩戴口罩对静息态和任务激活的影响很小或没有显著影响。
