【摘要】 用¹³¹Ⅰ—RB^*扫描测定肠—胃胆汁返流共45例,正常人8例,胃肠道疾病伴有胆汁返流患者37例,全部经胃镜检查证实。45例¹³¹Ⅰ—RB 扫描结果经判断矩阵分析方法处理,灵敏度达94.6%,特异性87.5%,准确率93.3%。同时部分正常与受检者在扫描结束后抽胃液测放射性计数,结果表明有胃内胆汁返流者,其胃液之放射性计数明显高于正常组,两组相比有显著差异,（P<0.01）。结论认为¹³¹Ⅰ—RB 扫描测定肠—胃胆汁返流是一种有一定准确性既方便又灵敏的方法。更多还原

【Abstract】 Measurement of intestinal-gastric bile reflux by ¹³¹I-RB scintigraphy was studied in 45 persons,of them,8 were normal and 37 were patients. All were examinated with Gastrofiberscope.The results were analysed with decission matrix:sensitivity 94.6%,specitivity 87.5%,and accuracy rate 93.3%.The result showed that the radiation counts of gastie juice in patients were obviously higher than that in normal subjects.（P<0.01）更多还原
