Gastric Emptying Study A gastric emptying system is a procedure that is done by nuclear medicine physicians using radioactive chemicals. It measures the speed in which food is digested. What they do is they put a scanner over the patient's stomach to monitor the amount of radioactivity in the stomach. They also lay you on a table and a gamma ray camera will obtain images of the stomach, and also detect energy level. During this procedure they use all sorts of lustrous,malleable and ductile metals.They also use radioactive tracers. A radioactive tracer is a chemical compound in which more than one atom has been replaced by radio-isotope.
