Abstract
MR imaging studies of the upper abdomen have been difficult to interpret due to the frequent inability to differentiate between various structures, especially between the [human] gastrointestinal tract and adjacent normal and pathological structures. Utilizing effervescent granules and i.v. glucagon, gas in the stomach and duodenum provides excellent contrast and results in improved MR imaging of the upper abdomen. This technique is useful in demonstrating both gastric and pancreatic morphology.
