Improving quality of magnetic resonance cholangiopancreaticography: esomeprazole versus ranitidine.

Background/aims: The aim of this study was to evaluate the effect of Ranitidine and Esomeprazole on the pancreatico-biliary tree and to define their role in improving visualization quality on magnetic resonance cholangiopancreaticography images.

Methodology: Magnetic resonance cholangiopancreaticography was done on 70 volunteers before and after using ranitidine for half of them and esomeprazole for the other half of the group. The images were evaluated for contrast effect (signal from stomach and duodenum), and image effect (conspicuousness) at various segments of pancreaticobiliary tree.
