| Comment: -Water is an ideal
oral contrast agent for gastric studies. It allows detection of smaller
lesions and tumor spread. I have tried arterial phase imaging in the stomach,
but it has no additional value. Oral contrast: 750 cc of flavored water
30 minutes prior to the study, and 250 cc at the time of the study. |
