title: Technetium-99m pertechnetate scan for ectopic gastric mucosa in children with gastrointestinal bleeding.
abstract: The detectability of ectopic gastric mucosa by Technetium (Tc)-99m pertechnetate abdominal scanning was investigated by reviewing 62 such scans in 52 pediatric patients with gastrointestinal hemorrhage. The histologic diagnoses and clinical conditions were correlated to the findings of the scans. There were 21 true-positives, 35 true-negatives, one false-positive and five false-negative studies. The overall sensitivity of this scan for the detection of ectopic gastric mucosa was 81%, the specificity was 97% and the accuracy was 90%.
