Real-time precision functional network mapping of the human brain for neurosurgical applications

于2022财政年度，我们扫描了另外10名健康志愿者，完成了所有20名健康对照者的MRI扫描。所有参与者都接受了两次成像，间隔约一个月。采集的MRI数据包括结构T1 MRI数据、一小时静息状态功能MRI数据和弥散加权MRI数据。此外，我们还获得了原发性震颤患者的MRI数据。对从健康对照组获得的数据集的初步分析表明，随着更多体积被纳入分析，全脑FCOR图的可靠性表现出初始快速增加。随着更多体积的添加，可靠性测量稍后达到平台，这表明可靠性的上限以及达到该限制的最佳体积数量。我们还开始分析原发性震颤患者的数据。此将于二零二三年财政年度完成。

For the FY2022, we have scanned 10 more healthy volunteers, completing the MRI scans of all 20 healthy controls. All participants underwent two imaging sessions, about one month apart. Acquired MRI data includes structural T1 MRI data, an hour of resting state functional MRI data, and diffusion-weighted MRI data. Additionally, we have also acquired the MRI data from patients with essential tremor. Preliminary analysis of the acquired datasets from healthy controls have shown that the reliability of the whole-brain FCOR map exhibited an initial rapid increase as more volumes are incorporated into the analysis. With more volumes added, the reliability measure later plateaus suggesting an upper limit to the reliability as well as an optimal number of volumes to achieve this limit. We have also started the analysis of the data from patients with essential tremor. This will be completed in FY2023.
