识别有意义的功能磁共振成像 (fMRI) 生物标志物需要采取措施，可靠地捕获不同受试者和多次扫描过程中的大脑表现。 fMRI 采集的最新发展，例如引入多频带 (MB) 协议和面内加速，可以提高扫描速度并提高时间分辨率。然而，它们也可能导致时间信噪比降低以及同时激发的切片之间的信号泄漏增加。这些方法已被多种扫描方式采用，包括弥散加权成像和功能磁共振成像。据我们所知，还没有研究正式比较传统单波段 fMRI 和不同 MB 采集（有或没有面内加速）下三个会话中相同静息态 fMRI (rs-fMRI) 指标（低频波动幅度；种子到体素和感兴趣区域 [ROI] 到 ROI 连接）的可靠性。在这项研究中，24 名健康老年人在第 0、1 和 4 周进行了 3 次扫描，每次都接受了传统的单波段 rs-fMRI 扫描和 3 次不同的 rs-fMRI 扫描，MB 因子为 4 和 6，有或没有平面内加速。在所有三个 rs-fMRI 指标中，MB 因子 4（皮层区域无平面内加速）和传统单带皮层下区域的可靠性得分最高。讨论了对未来研究的建议。我们比较了四种不同静息态模式和超过 3 次就诊的三种静息态 fMRI 指标的重测可靠性。没有面内加速的多频带因子 4 显着改善了皮质区域的组内相关系数 (ICC) 分数，而单频带则为皮质下区域产生了最佳 ICC 值。对于全脑分析或针对特定皮质区域的分析，我们建议使用不带面内加速的多波段因子 4，对于重点关注皮质下区域的研究，建议使用单波段。
The identification of meaningful functional magnetic resonance imaging (fMRI) biomarkers requires measures that reliably capture brain performance across different subjects and over multiple scanning sessions. Recent developments in fMRI acquisition, such as the introduction of multiband (MB) protocols and in‐plane acceleration, allow for increased scanning speed and improved temporal resolution. However, they may also lead to reduced temporal signal to noise ratio and increased signal leakage between simultaneously excited slices. These methods have been adopted in several scanning modalities including diffusion weighted imaging and fMRI. To our knowledge, no study has formally compared the reliability of the same resting‐state fMRI (rs‐fMRI) metrics (amplitude of low‐frequency fluctuations; seed‐to‐voxel and region of interest [ROI]‐to‐ROI connectivity) across conventional single‐band fMRI and different MB acquisitions, with and without in‐plane acceleration, across three sessions. In this study, 24 healthy older adults were scanned over three visits, on weeks 0, 1, and 4, and, on each occasion, underwent a conventional single band rs‐fMRI scan and three different rs‐fMRI scans with MB factors 4 and 6, with and without in‐plane acceleration. Across all three rs‐fMRI metrics, the reliability scores were highest with MB factor 4 with no in‐plane acceleration for cortical areas and with conventional single band for subcortical areas. Recommendations for future research studies are discussed. We compared the test–retest reliability of three resting‐state fMRI metrics across four different resting‐state modalities and over three visits. Multiband factor 4 with no in‐plane acceleration significantly improved intraclass correlation coefficient (ICC) scores for cortical areas, while single band yielded the best ICC values for subcortical regions. We recommend multiband factor 4 with no in‐plane acceleration for whole brain analyses or analyses focussing specifically cortical regions, and single band for studies with an emphasis on subcortical areas.
