The Neurodevelopmental MRI Database

项目总结/摘要 科学家使用神经成像工具，如MRI，NIRS，EEG和MEG，使用平均MRI模板来定位大脑 结构（立体定位地图集），结合不同参与者的大脑，分割先验以识别 皮质组织（灰质、白色物质、CSF），以及确定头皮位置和大脑之间的关系（例如， EEG、NIRS、MEG）。通常使用的平均MRI模板基于单个成人MRI或平均 年轻人的模板。将这些模板用于儿科（新生儿、婴儿、儿童）、青少年和老年人 群体导致不规则的登记，分割数据的错误指定，以及立体定位图谱的不佳拟合。的 “神经发育MRI数据库”的创建就是为了解决这个问题。它提供了MRI模板，从2周到 89岁，以及支持材料（分割先验，地图集，EEG和NIRS放置）。将数据 以细粒年龄呈现（例如，1.5 1年内间隔1个月; 19.5年内间隔6个月; 5年 从20岁到89岁）。目前的项目将增加新的参与者的平均MRI模板，完善 MRI更广泛地用于MRI处理程序，并计划从分发到PI在线存储的过渡 网站到一个开放访问的分发网站。该项目将加强现有的数据，并促进这方面的共享。 重要资源。

Project Summary / Abstract Scientists using neuroimaging tools, such as MRI, NIRS, EEG, and MEG, use average MRI templates for locating brain structures (stereotaxic atlases), combining brains across different participants, segmenting priors for identification of cortical tissues (gray matter, white matter, CSF), and determining the relation between scalp locations and the brain (e.g., EEG, NIRS, MEG). Average MRI templates that are usually used have been based on single adult MRIs or average templates from young adults. Use of these templates with pediatric (newborns, infants, children), adolescent, and elderly populations results in irregular registrations, misspecification of segmented data, and poor fits for stereotaxic atlases. The “Neurodevelopmental MRI Database” was created to address this issue. It provides MRI templates form 2 weeks through 89 years of age, as well as supporting materials (segmenting priors, atlases, EEG and NIRS placements). The data are presented in fine-grained ages (e.g., 1.5 month intervals through 1 year; 6 month intervals through 19.5 years; 5 year intervals from 20 through 89 years). The current project will add new participants to the average MRI templates, refine the MRIs for wider use with MRI processing programs, and plan a transition from distribution through the PI's online storage site to an open-access distribution site. This project will enhance the current data and facilitate the sharing of this important resource.
