放射性核素胃食管显象测定胃食管返流

The Eletermiation of GER Using Gastroesophageal Image in Technique

放射性核素胃食管显象诊断胃食管返流具有方法简便、灵敏、非侵入性、定量等优点。作者用本法检测１８例正常人均未见返流，８４例胃食管返流可疑病人检出率为７８．６％，而胃肠Ｘ线钡剂和内窥镜检查的检出率仅为７０．２％，和２６．０％，分别为放射性核素显象检出率的８９．３％和３３．１％。

The Diagnosis of gastroesphageal reflux (GER) using radionuclide imaging is a simple, sensitive, non-invasive and quantitative technique. This paper reported the results of 18 normal persons and 84 cases of suspected GER patients examined by this technique. No reflux was found in normal group, there were 78.6% detectability in patients group, while the detectability X-ray examination were 70.2% in same group of patients. 23 cases were undergoing endoscopic examination,only 6 cases had revealed the presence of reflux, thereby eletectability was only 26.0%.
