The Working Group on Virtual Colonoscopy published in 2005 a guide to the interpretation of computed tomography (CT) colonography results: the CT Colonography Reporting and Data System (C-RADS). It includes a Description of Terms for reporting the size, morphologic features, and location of polyps and masses, a Description of a Reporting Scheme for Colonic and Extracolonic Lesions with Management Recommendations.
BIOPROGNOS has already implemented ―for training or educational purposes― C-RADS for Colorectal Cancer screening and detection. Use is free of charge and not limited.

Once entered the patient data, our C-RADS Score Calculator for CT Colonography presents the results as a PDF document, that can be downloaded or sent by email.
The report includes all Patient Data as well as Score, calculated according last version of C-RADS.
