However, the main disadvantage of computed tomography (CT)<\/jats:styled-content> compared with magnetic resonance imaging (MRI)<\/jats:styled-content> is radiation exposure and the potential risk of cancer, especially since IBD<\/jats:styled-content> patients are at increased risk of malignancies. This study aims to quantify and characterize effective radiation exposure of IBD<\/jats:styled-content> patients.<\/jats:p><\/jats:sec>Methods<\/jats:title>A cohort of IBD<\/jats:styled-content> patients were retrospectively enrolled in the Cl\u00ednica las Condes IBD registry between 2011 and 2013.
