The Open Access Series of Imaging Studies (OASIS) is a project aimed at making neuroimaging data sets of the brain freely available to the scientific community. By compiling and freely distributing neuroimaging data sets, we hope to facilitate future discoveries in basic and clinical neuroscience.
About the OASIS Brains project
OASIS-3 and OASIS-4 are the latest releases in the Open Access Series of Imaging Studies (OASIS) that is aimed at making neuroimaging datasets freely available to the scientific community. By compiling and freely distributing this multimodal dataset generated by the Knight ADRC and its affiliated studies, we hope to facilitate future discoveries in basic and clinical neuroscience. Previously released data for OASIS-Cross-sectional (Marcus et al, 2007) and OASIS-Longitudinal (Marcus et al, 2010) have been utilized for hypothesis driven data analyses, development of neuroanatomical atlases, and development of segmentation algorithms. OASIS-3 is a longitudinal multimodal neuroimaging, clinical, cognitive, and biomarker dataset for normal aging and Alzheimer’s Disease. OASIS-4 contains MR, clinical, cognitive, and biomarker data for individuals that presented with memory complaints.
The OASIS datasets hosted by NITRC-IR provide the community with open access to a significant database of neuroimaging and processed imaging data across a broad demographic, cognitive, and genetic spectrum an easily accessible platform for use in neuroimaging, clinical, and cognitive research on normal aging and cognitive decline.
Summary: This set consists of a cross-sectional collection of 416 subjects aged 18 to 96. For each subject, 3 or 4 individual T1-weighted MRI scans obtained in single scan sessions are included. The subjects are all right-handed and include both men and women. 100 of the included subjects over the age of 60 have been clinically diagnosed with very mild to moderate Alzheimer’s disease (AD). Additionally, a reliability data set is included containing 20 nondemented subjects imaged on a subsequent visit within 90 days of their initial session.
Summary: This set consists of a longitudinal collection of 150 subjects aged 60 to 96. Each subject was scanned on two or more visits, separated by at least one year for a total of 373 imaging sessions. For each subject, 3 or 4 individual T1-weighted MRI scans obtained in single scan sessions are included. The subjects are all right-handed and include both men and women. 72 of the subjects were characterized as nondemented throughout the study. 64 of the included subjects were characterized as demented at the time of their initial visits and remained so for subsequent scans, including 51 individuals with mild to moderate Alzheimer’s disease. Another 14 subjects were characterized as nondemented at the time of their initial visit and were subsequently characterized as demented at a later visit.
Summary: 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. Additionally, 451 Tau PET sessions and post-processed PUP are now available for OASIS-3 subjects in a sub-project ‘OASIS-3_AV1451’.
Summary: An additional 451 Tau PET sessions and post-processed PUP are now available for OASIS-3 subjects in a sub-project ‘OASIS-3_AV1451’.
This dataset requires a unique data request at the following link: https://sites.wustl.edu/oasisbrains/home/oasis-3/request-tau-access/
Summary: This set consists of a collection of 663 subjects aged 21 to 94. This clinical cohort was evaluated for memory disorders and dementia including clinical, csf, neurospychometric, and neuroimaging assessments.
This is a unique OASIS dataset and not an update to the OASIS-3 Longitudinal Multimodal Neuroimaging datasets.
Data Use Terms
The OASIS data are distributed to the greater scientific community under the following terms:
- User will not use the OASIS datasets, either alone or in concert with any other information, to make any effort to identify or contact individuals who are or may be the sources of the information in the dataset. If User inadvertently receives identifiable information or otherwise identifies a subject, User will promptly notify OASIS and follow OASIS’s reasonable written instructions, which may include the return or destruction of identifiable information.
- User is strictly prohibited from generating or using images or comparable representations of the face, head, or body for facial recognition, re-identification, or other purposes that could allow the identities of research participants to be readily ascertained.
- User will not use or further disclose the OASIS-3 or OASIS-4 other than as permitted by this agreement or as otherwise required by law. Additionally, User will not use or further disclose any derivative works or derivative data of the OASIS datasets, in any case in whole or in part, that could be used to reconstruct a facial image. User shall report to OASIS promptly upon User’s discovery of any unauthorized use or disclosure not permitted by this License. User shall provide the following information: (1) the nature of the use or disclosure; (2) the information used or disclosed; (3) the identity of the persons and/or entities that made the use or disclosure; and (4) what corrective action will be taken by User as a result of the use or disclosure. User shall take any other reasonable actions available to it to mitigate any detrimental effects of the use or disclosure.
- User will acknowledge the use of OASIS data and data derived from OASIS data when publicly presenting any results or algorithms that benefitted from their use.
