Core Tip
Core Tip: The treatment response to infliximab in patients with Crohn's disease (CD) is heterogeneous, with approximately 23%-46% of those achieving clinical remission after induction therapy experiencing secondary loss of response (SLR) within the first year. This significantly increases the risk of serious adverse outcomes. In this study, we developed a delta-radiomics model based on longitudinal changes in visceral adipose tissue assessed through computed tomography enterography. This model further integrates clinical and imaging biomarkers to identify patients with CD at high risk of SLR. This non-invasive approach holds promise as a valuable tool for optimizing personalized treatment regimens and guiding monitoring strategies.
