“…Based on the American Neurogastroenterology and Motility Society and the Society of Nuclear Medicine recommendations, ours and other protocols can be simplified by reducing GES imaging to 4 time points (0, 60, 120, and 240 minutes). An abbreviated protocol can help scheduling and permit more efficient use of imaging equipment, allowing multiple GES to be performed on 1 camera in a single day if the starting times are staggered (4,15). The radiation exposure associated with the gastric emptying scintigraphy study is extremely low (0.006-0.012 mSv) and is comparable with that from natural background radiation exposure in 1 month.…”
