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.
采用液体和固体胃排空闪烁扫描法对21名志愿者的正常模式进行了研究。其中，19人进行了固体排空研究，14人进行了液体排空研究。液体研究持续半小时，而固体研究持续1小时。记录了胃排空半衰期（T1/2）以及15分钟时（液体）和60分钟时（固体）的潴留百分比。时间-活性曲线也针对组织衰减进行了校正。结果表明，正常平均液体排空T1/2为14.2分钟，而固体排空T1/2为116分钟。
