Inflammatory bowel disease Crohn's disease CR enterography MRI enterography a b s t r a c t Crohn disease is defined as a chronic inflammatory and idiopathic process that can affect any portion of the gastrointestinal tract. The small intestine is the most frequently affected place, so small bowel morphology investigation is often mandatory. For decades small bowel was almost inaccessible to endoscopies, and, studies like enteroclysis and bowel transit time test, were considered gold standard

Authors review literature, concerning the role of computed tomography enterography and magnetic resonance enterography in the evaluation of small bowel Crohn disease. Authors conclude that the choice of examination to be made should be weighted considering several factors such as the age of the patient, their tolerability, the Crohn's disease phenotype and the availability of hospital resources. is an open access article under the CC BY-NC-ND license (http://creativecommons.org/ licenses/by-nc-nd/4.0/). Enterografia por tomografia computorizada e por ressonância magnética na avaliação da Doença de Crohn do intestino delgado Palavras-chave: Doença inflamatória intestinal Doença de Crohn Enterografia por TC Enterografia por IRM r e s u m o A doença de Crohn é definida como um processo inflamatório e idiopático crônico que pode afetar qualquer parte do trato gastrintestinal. O intestino delgado é o local mais frequentemente afetado e, assim, com frequência torna-se obrigatória uma investigação da morfologia do intestino delgado. Durante décadas, o intestino delgado era praticamente inacessível às endoscopias; nesse contexto, estudos como a enteróclise e a determinação do tempo de trânsito intestinal eram
