To evaluate accuracy and cost of non-invasive diagnostic strategies including magnetic resonance imaging, intestinal ultrasonography, ileocolonoscopy and video-capsule endoscopy in suspected Crohn s disease. Methods: A decision-analytic model was used to assess the costs in low (25 ), intermediate (50 ) or high (75 ) pre-test probability of Crohn s disease. Based on the published accuracy of diagnostic modalities and Bayes rule, we calculated post-test probability of Crohn s disease using different strategies, starting from ileocolonoscopy, ultrasonography or magnetic resonance. Each strategy was considered successful when post-test probability was >. 95 or
