目前认为双标记同位素闪烁照相法是同步检测胃固相和液相排空的“金标准”,但闪烁照相法耗时,需要昂贵的仪器(γ-照相机),且因有放射性而难以广泛开展。近年来稳定性同位素被试用于检测胃排空。由~(13)C-标记的呼吸试验与闪烁照相法所得的参数具有非常好的相关性。本实验的目的是研究~(13)C-标记的呼吸试验
Dual-labeled isotope scintigraphy is currently considered the “gold standard” for simultaneous detection of gastric and liquid phase emptying, but the scintigraphy method is time-consuming and requires expensive equipment (gamma-camera) and is difficult to extensively develop due to radioactivity . In recent years, stable isotopes were used to detect gastric emptying. The parameters obtained by the ~ (13) C-labeled breath test and scintigraphy had a very good correlation. The purpose of this experiment was to study the ~ (13) C-labeled respiration test
