ABSTRACT

Introduction: image techniques play an important role in the diagnosis of inflammatory bowel diseases and computerized tomography constitutes a novel technique due to its wide scope.
Objectives: to describe the importance of computed tomography in the assessment of inflammatory bowel disease and identify the tomographic findings by means of characterising features of Crohn´s disease.
Material and Methods: it was made a review through automatized data base MEDLINE (PubMed as search engine) using computed tomography enterography, computed tomography enteroclysis and Crohn´s disease as descriptors. The review was based on the critical analysis of relevant publications, most appearing from 2007 to 2012.
Development: in the present revision article, we carried out a comparative approach of the main imaging techniques used in the inflammatory bowel disease pointing out the usefulness of computed tomography to evaluate the wall and extraluminal lesions and the main tomographic findings in the diagnosis, evolution and their complications were stated taking the Crohn´s disease as an entity type.
Conclusions: computed tomography is a novel imaging study in the assessment of inflammatory bowel disease which goes beyond conventional imaging investigations. New generations of multislice computed tomography may provide a better assessment of structural morphologic changes.
