Your doctor has recommended that you have a gastric emptying study, which measures the speed with which food leaves the stomach and enters the small intestine. Gastric emptying studies are done to diagnose symptoms that may be related to slow or rapid emptying of the stomach. Our team of specialized doctors, nurses and technologists that performs gastric emptying studies is led by Alan Waxman, MD, chair of Nuclear Medicine.

During the Exam
- For a gastric emptying study, you will be asked to eat a meal with a solid and a liquid component mixed with a tiny amount of radioactive material.
