58 children with gastrointestinal bleeding were examined for ectopic gastric mucosa with 99m Tc-pertechnetate. 25 cases who had abnormal uptake in 1 hour were diagnosed positive and among them 17 cases were operated on and final pathology diagnoses were made- The results showed that 5cases were Meckel’s diverticulum, 8 alimentary duplication aberrations and 4 false positive inclusive of 1 enteric hemangioma and 1 enteric telangiectasia. From the results, duplications were more than Meckel’s diverticulum which contained gastric mucosa. False positive can be avoided by using the early uptake phase and twice image in the first hour as diagnostic standard except enteric hemangioma and enteric teiangiectasia.
