目的:探讨99TcmO4-异位胃黏膜显像在小儿Meckel’s憩室诊断的临床应用。方法:对37例消化道出血患儿应用99TcmO4-进行异位胃黏膜显像,采集动态相及多时相静态显像,并与手术病理相对比。结果:37例患儿中20例99TcmO4-异位胃黏膜显像呈阳性,病变为圆形或类圆形异常放射性增高区,多位于脐周或右下腹部,位置相对固定。显像敏感性为70.0%,特异性为94.1%,阳性预测值为93.3%,阴性预测值为72.7%,准确度为87.5%。结论:99TcmO4-异位胃黏膜显像对小儿Meck-el’s憩室诊断具有病因及定位诊断价值,应成为辅助检查首选。
Objective: To investigate the clinical application of 99TcmO4-ectopic gastric mucosa imaging in the diagnosis of Meckel’s diverticulum in children. Methods: Ectopic gastric mucosa imaging was performed on 99TcmO4- in 37 children with gastrointestinal hemorrhage. Dynamic and multiphase static images were collected and compared with the surgical pathology. RESULTS: Twenty cases of 99TcmO4-ectopic gastric mucosa were positive in the 37 cases. The lesions were abnormally orbicular abnormally elevated areas, mostly in the umbilical or lower right abdomen, with a relatively fixed position. The imaging sensitivity was 70.0%, the specificity was 94.1%, the positive predictive value was 93.3%, the negative predictive value was 72.7%, and the accuracy was 87.5%. Conclusion: 99TcmO4-ectopic gastric mucosa imaging has diagnostic value for the diagnosis of Meck-el’s diverticular disease in children and should be the first choice for the auxiliary examination.
