Radionuclide studies of the gastrointestinal tract (GI) are used to measure GI function and to detect anatomic lesions such as Meckel's diverticuli. A variety of physiological and pharmacological interventions have been applied to both types of studies to gain a better understanding of GI function and to improve detection of disease. This article will review interventions useful in imaging the tubular GI tract. Discussed are the measurement of GI motility and function by gastric emptying and imaging studies for GI bleeding including the Meckel's scan. Interventions involving the hepatobiliary system are covered elsewhere in this issue.
胃肠道的放射性核素研究用于测量胃肠功能并检测诸如梅克尔憩室等解剖学病变。多种生理和药理干预措施已应用于这两类研究，以更好地了解胃肠功能并改善疾病检测。本文将综述对管状胃肠道成像有用的干预措施。讨论的内容包括通过胃排空测量胃肠动力和功能以及用于胃肠出血的成像研究，包括梅克尔扫描。涉及肝胆系统的干预措施在本期其他地方介绍。
