Gastric emptying study has an important role in patients with gastrointestinal functional disorders without demonstrable mechanical or mucosal abnormalities. Although several meth- ods for detection on gastrointestinal functional disorders are well known, non-invasive scintigraphic technique using a Gamma Camera is taken as a gold standard at present. A Dual-Head Gamma Camera coupled to a computer was used in 20 normal subjects after in- gestion of the mixture of '""'T,-labelled scrambled egg in order to determine gastric emptying time. Four values including lag time, T,,(half gastric emptying time), remnant 1 hour, remant 2 hours were taken at all ages. In the female half gastric emptying time and lag time was slightly shorter, and the amount of remnant radioactive counts at one and two hours was smaller than the I,aale without significant difference. Delayed gastric emptying time was above 109. 9 minutes of half gastric emptying time when defined as excess of Mean+ZSD". W e believe this study using a Dual-Head Gamma Camera can be useful for establishment of more accurate gastric emptying study.(Korean J Gastroenterol 1994; 26: 2Z4 229)
