Resumen

CSENDES G, Paula et al. INTESTINO DELGADO PATOLOGICO: RESONANCIA MAGNETICA CON CONTRASTE ORAL VERSUS TRANSITO INTESTINAL CON BARIO (RESULTADOS PRELIMINARES. Rev. chil. radiol. [online]. 2004, vol.10, n.4, pp.158-164. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082004000400003.

Small bowel transit with barium sulphate allows adequate visualization of endoluminal alterations, but with drawbacks such as limited usefulness for wall compromise and extra parietal extension. Magnetic resonance appears to be an alternative, given its benefits avoiding radiation and allowing evaluation of anatomic details of the small bowel and adjacent structures. Eleven patients with abnormal result of intestinal transit with barium underwent magnetic resonance with water 1500 cc p.o in brief period, with images achieved in a 1.5 Tesla resonator, with 25 mT/m gradient, using optimized sequences. Comparison in regards of time of transit, distension, and characterization of pathology was made. An adequate correlation of the pathologic small bowel and its adjacent structures is achieved with magnetic resonance compared with transit with barium, achieving 90.9% of simple correlation and 0.82 Kappa value (excellent correlation), making this technique a valid and effective alternative to the conventional study of the small bowel with barium in our experience. Larger series are required to confirm this
