  • Title: Quantitative radioisotope measurement of duodenogastric reflux in patients with ulcer or gastrectomized for ulcer.

    Journal: Nuklearmedizin; 1985 Jun; 24(3):107-10. PubMed ID: 4059061.
    Abstract:
    In this work the duodenogastric reflux was quantified as the amount of radioactivity entering the stomach after an i.v. administration of 99mTc-HIDA in ulcer patients and in patients who had undergone BI gastrectomy. The results were compared with visual evidence of gastric activity in the gamma camera images and biochemical determination of gastric bile reflux. The method is useful in quantifying the reflux if the activity is above the background activity. It allows the determination of an upper limit for the reflux when the reflux is evident visually. Only two or three images are needed for the quantitation. No correlation was found between biochemical measurement of fasting bile reflux in the stomach and radioisotopic quantification.
