What is XNAT? »

XNAT is an open-source imaging informatics software platform dedicated to helping you perform imaging-based research. XNAT’s core functions manage importing, archiving, processing and securely distributing imaging and related study data. But its extended uses continue to evolve.

XNAT for Institutional Repositories »

Create a centralized data management resource to support multiple investigators and research studies. How many? As many as you need. (A single XNAT at Washington University in St Louis currently supports 800 separate projects with 16,000 subjects and 20,000 imaging sessions, and is steadily growing.)

XNAT for Clinical Research Hubs »

Enable the translation of research findings to clinical practice by using a single XNAT system to store both clinical imaging and assessments alongside your research projects.

XNAT for Multi-center Studies »

Use XNAT’s flexible image importing, built-in reporting, data oversight and quality assurance functions to aggregate data from multiple far-flung research sites. Without tearing your hair out in the process.

XNAT for Data-Sharing Services »

Choose the size of your megaphone, and broadcast your data. Use XNAT for sharing data selectively among collaborators, or publicly to the world at large.
