Belly fat is reported to have an important role in Crohn's disease progression. This makes belly fat a potential therapeutic target that can be influenced by the external environment including the gut microbiota and diet. In this study, we validate the use of imaging as a non-invasive diagnostic tool for measuring inflamed belly fat in people with Crohn's disease. The imaging tool can be used to assess the effectiveness of different therapies on belly fat to improve outcomes for sufferers of Crohn's disease.
