The assessment of gastric emptying rates by radionuclide labeled test meals has been developing over the past decade. Some investigators have advocated the use of two γ counters positioned anteriorly and posteriorly to the stomach to attain accurate measurements. Theoretical considerations and phantom studies presented herein demonstrate that a single γ counter may be used with acceptable accuracy. Application of the technique described will allow for the clinical assessment of gastric emptying in virtually any nuclear medicine department.
