Core Tip

Core Tip: The opportunities that arise from the application of artificial intelligence/machine learning-based models in gastroenterology and hepatology include the establishment of targeted screening programs through the identification of patients prone to develop cancer, the development of non-invasive diagnostic tools, the improvement of the diagnostic accuracy, the development of treatment allocation frameworks based on predictions of outcomes for different treatment modalities, the development of models to ensure cost-effective use of resources, the development of triage tools for higher levels of care and decision-making tools for further treatment, based on individualized patient outcome predictions, and finally the development of predictive models of prognosis for patient and family counseling.
