Nuclear medicine is the application of tracer methodology mainly to clinical diagnosis. We use chemical compounds labelled with radioisotopes as tracers. The examinations provide us with the information on regional function of tissues and organs. In this review we describe the nuclear medicine procedures for the diagnosis of gastrointestinal diseases based on our experiences. The emphasis is put on the evaluation of the functional aspect of the gastrointestinal tract. The procedures to be described include diagnosis of Meckel's diverticulum by gastric mucosal scintigraphy, measurement of esophageal, gastric and intestinal transit, detection of portocaval shunt and measurement of lactose absorption and detection of bacterial deconjugation of bile salts by means of breath analysis technique.
核医学主要是将示踪剂方法应用于临床诊断。我们使用用放射性同位素标记的化合物作为示踪剂。这些检查为我们提供有关组织和器官区域功能的信息。在本综述中，我们根据自身经验描述用于诊断胃肠道疾病的核医学程序。重点在于评估胃肠道的功能方面。所描述的程序包括通过胃黏膜闪烁显像诊断梅克尔憩室、测量食管、胃和肠道的通过时间、检测门体分流以及通过呼吸分析技术测量乳糖吸收和检测胆汁盐的细菌去结合作用。
