What position does the body have to be in to view the fundus of the stomach in fluoroscopy?

Supine
Upright
Prone
Left Posterior Oblique (LPO)

The correct answer is: Left Posterior Oblique (LPO)

To visualize the fundus of the stomach during a fluoroscopy procedure, positioning the patient in the Left Posterior Oblique (LPO) position is optimal. This position allows for the stomach's fundus, which is located on the left side of the body, to be positioned higher and more clearly in view. The oblique orientation helps to minimize superimposition of surrounding structures, providing a clearer image of the fundus. In the LPO position, the left side of the body is elevated, which promotes the delineation of the fundus and allows for better visualization of gastric air, fluid levels, and potential lesions. This positioning takes advantage of the anatomical relationships and gravitational effects, making it the best choice for obtaining detailed imaging of the upper gastrointestinal tract, particularly the fundus region. Other positions, such as supine or upright, may not provide the same level of detail and clarity for this specific area of interest.
