Sémiologie radiologique endoluminale et en coupes du tube digestif

Barium studies as endoscopy provide exquisite delineation of mucosal pathologic features. The precise description of radiographic characteristics in conjunction with site and size of the lesion and the clinical history enables the radiologist to formulate a specific diagnosis or a graded differential diagnosis. Although mucosal abnormalities and small mass lesion are beneath its spatial resolution, sonography like computed tomography (CT) and MR Imaging excels in demonstrating the extramucosal component of gastrointestinal tract disease and in detecting extra intestinal complications.
