Summary
The Central Neuroimaging Data Archive (CNDA) at Washington University supports over 1000 studies, offering diverse neuroimaging data, including MR and PET scans. A portion of this valuable research data is accessible to external scientists upon request.
Area of Science:
- Neuroimaging Informatics
- Biomedical Data Archiving
Background:
- The Central Neuroimaging Data Archive (CNDA) at Washington University has facilitated neuroimaging research since the early 2000s.
- CNDA is built on XNAT, an open-source platform that originated from CNDA's codebase.
- It archives data from over 1000 studies, involving 36,000 subjects and 60,000 imaging sessions.
Purpose of the Study:
- To provide an overview of the CNDA's capabilities and data holdings.
- To highlight the accessibility of CNDA data for external research collaborations.
Main Methods:
- The CNDA utilizes an XNAT-based imaging informatics system.
- It hosts a wide array of imaging modalities, predominantly Magnetic Resonance (MR) and Positron Emission Tomography (PET) of the human brain.
- Data includes imaging sessions, and in some cases, associated clinical, psychometric, tissue, or genetic information.
Main Results:
- CNDA supports a vast repository of neuroimaging data from diverse research studies.
- The archive includes various imaging modalities, with a focus on brain MR and PET.
- Approximately 20% of CNDA's data is available to external researchers by request.
Conclusions:
- The CNDA serves as a critical resource for neuroimaging research, offering extensive data from numerous studies.
- Its data, particularly brain MR and PET, supports research in areas like Alzheimer's disease, metabolism, cancer, HIV, sickle cell anemia, and Tourette syndrome.
- The availability of CNDA data to external researchers fosters broader scientific collaboration and discovery.
