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%.
通过回顾52例患有胃肠道出血的儿科患者的62次锝(Tc)-99m高锝酸盐腹部扫描,研究了异位胃黏膜的锝(Tc)-99m高锝酸盐腹部扫描的可检测性。组织学诊断和临床情况与扫描结果相关。有21例假阳性、35例假阴性、1例假阳性和5例假阴性研究。该扫描检测异位胃黏膜的总体敏感性为81%,特异性为97%,准确性为90%。
