Validation of Plant-Based Vegan Meal for Gastric Emptying Testing in 10 Healthy Subjects

"After the radiolabeled breakfast meal is ingested, the participant is positioned upright between the two detectors of the Brightview system (Phillips Medical Systems, Cleveland, OH). Detector height is adjusted to include esophageal uptake, the stomach, and the small bowel. Anterior and posterior static images are acquired at 2 minutes per image using a 256 x 256 word mode matrix. Anterior and posterior images are again acquired at 1 and 2 hours post-ingestion of the radiolabeled breakfast meal.~The participant is then given the designated 'push' meal after completion of the 2-hour images. At 4 hours post-ingestion, images are acquired in the same manner as at previous time points."
