Question

During an upper GI exam, a stomach of average shape demonstrates a barium filled fundus and double contrast of the pylorus and duodenal bulb. The position used is most likely ?

Answer 1

In an upper GI exam with a barium-filled fundus and double contrast of the pylorus and duodenal bulb, the left lateral decubitus position is most likely used to achieve clear and contrasted imaging.

Step-by-step explanation:

During an upper GI exam, if a stomach demonstrates a barium-filled fundus with double contrast of the pylorus and duodenal bulb, the most likely position used is the left lateral decubitus position. This position allows for the barium to fill the fundus due to gravity, showing a clear view of the gastric anatomy. It also provides a double contrast effect for the pylorus and duodenal bulb, which are visualized due to their positioning and the presence of gas that's usually introduced during the procedure to achieve this contrast.
