Objective To develop a method of measuring small bowel transit time (SBTT) by 99 Tcmsulfur collid (SC) imaging and to compare with the method of added lactose in the test meal Methods 20 healthy volunteers and 26 patients with gastrointestinal disorders were studied In fasting state, the subjects were asked to ingest the 99 TcmSC labeled solid meal within 5 minutes, then the image acquisition was immediately started with SPECT The images were acquired every 15 min during the first hour, at 30 min intervals during 24 hours and hourly thereafter until 80% radioactivity had entered the colon One week later, the same procedure of imaging with 15 g lactulose added in the test meal was performed The regions of interest (ROIs) were taken at stomach and colon, and the SBTT was calculated by deconvolution or by subtraction of the 50% time of gastric emptying from the 50% time of colon filling Results The mean SBTT of 20 healthy volunteers was (4205) h, oralcaecum transit time (OCTT) was (4306) h; lactulose shortened the SBTT by (1806) h; 26 patients showed different results of SBTT due to their different gastrointestinal disorders bases Conclusions 99TcmSC imaging was a noninvasive and useful method to measure SBTT. The added lactulose can shorten the examination time and help to identify the time of food to the ileocecal region
