title: Radionuclide measurement of liquid and solid gastric emptying in normal subjects in Singapore.
abstract: Scintigraphic methods for liquid and solid gastric emptying were utilised to study normal patterns in 21 volunteers. Of these, 19 had solid emptying studies and 14 had liquid emptying studies. The liquid study lasted 1/2 hour, while the solid study was for 1 hour. The gastric emptying half-time (T 1/2), as well as percentage retention at 15 minutes (liquids), and at 60 minutes (for solids) were noted. The time-activity curves were also corrected for tissue attenuation. Results indicated normal average liquid emptying T 1/2 to be 14.2 minutes, while that for solids was 116 minutes.
