The Central Neuroimaging Data Archive, established in 2004, is the NRG’s flagship installation of XNAT, and supports multiple active research projects at Washington University in St Louis.
In mid-2009, the CNDA hosted 150 research studies with a combined total of 3000 subjects and around 6500 imaging sessions. Today we are the repository for well over 1000 research studies, 36,000 subjects and more than 60,000 imaging sessions. Most imaging modalities used in modern human research are represented in the CNDA, including:
- 1.5T and 3T magnetic resonance (MR)
- positron emission tomography (PET), with a variety of tracers
- computed tomography (CT)
- nuclear medicine (NM)
- computed radiography (CR)
- digital radiography (DX)
- ultrasound (US)
However, the majority of that data is MR and PET of the brain.
Like all instances of XNAT, the CNDA provides access to a secure database, automated pipelines for processing managed data, and tools for exploring and accessing the data. Additionally, researchers have the capability to create their own custom pipelines to handle specific image-processing tasks central to their research.
As our most heavily used instance of XNAT, the CNDA’s user group provides invaluable feedback toward the ongoing development and improvement of the XNAT system.
