The LI-RADS app implements the American College of Radiology's Liver Imaging Reporting and Data System (LI-RADS) logic. Users can input lesion characteristics for an arbitrary number of lesions, for which the appropriate LI-RADS category is derived.
As of version 1.2 the UNOS-OPTN lesion category is derived, and the LI-RADS schema is updated to v2014. Version 1.3 brings minor corrections to both algorithms.
The anticipated userbase is of radiologists and hepatologists, both of whom need accurate and quick lesion categorization.
