The use of a single gamma camera in radionuclide assessment of gastric emptying.
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 gamma counters positioned anteriorly and posteriorly to the stomach to attain accurate measurements. Theoretical considerations and phantom studies presented herein demonstrate that a single gamma 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.
