OASIS3

OASIS-3 is a retrospective compilation of data for 1378 participants that were collected across several ongoing projects through the WUSTL Knight ADRC over the course of 30years. Participants include 755 cognitively normal adults and 622 individuals at various stages of cognitive decline ranging in age from 42-95yrs. All participants were assigned a new random identifier and all dates were removed and normalized to reflect days from entry into study. The dataset contains 2842 MR sessions which include T1w, T2w, FLAIR, ASL, SWI, time of flight, resting-state BOLD, and DTI sequences. Many of the MR sessions are accompanied by volumetric segmentation files produced through FreeSurfer processing. PET imaging from different tracers, PIB, AV45, and FDG, totaling over 2157 raw imaging scans and the accompanying post-processed files from the Pet Unified Pipeline (PUP) are also available in OASIS-3.

OASIS-3 数据集为历时30年，由WUSTL Knight ADRC在多个持续进行的项目中收集的1378名参与者的数据进行了回顾性汇编。参与者包括755名认知正常的成年人以及622名处于不同认知退化阶段的个体，年龄范围在42至95岁之间。所有参与者均被分配了一个新的随机标识符，所有日期均被移除并标准化，以反映自研究入组之日起的天数。该数据集包含2842次MRI扫描，包括T1w、T2w、FLAIR、ASL、SWI、飞行时间、静息态BOLD和DTI序列。许多MRI扫描伴随有通过FreeSurfer处理生成的体积分割文件。此外，OASIS-3还提供了来自不同示踪剂的PET成像数据，包括PIB、AV45和FDG，总计超过2157张原始成像扫描及其伴随的Pet Unified Pipeline（PUP）后处理文件。
