Because of the difficulty often encountered in deciding whether a patient's symptoms originate in the upper or lower gastrointestinal tract, gastrointestinal transit scintigraphy is a uniquely suited noninvasive, quantitative, and physiologic method of determining whether there is a motility disorder affecting the stomach, small bowel, or colon. Small-bowel and colon transit studies can be performed alone or together with gastric emptying studies after oral administration of an appropriately radiolabeled meal. It is hoped that newly published standards for performing these studies and the anticipated arrival of new Current Procedural Terminology codes in the United States for small-bowel and colon transit studies will increase their availability and use.
由于在判断患者症状源于上消化道还是下消化道时常常遇到困难，胃肠道转运闪烁扫描术是一种特别适合用于确定是否存在影响胃、小肠或结肠的动力障碍的非侵入性、定量且生理学方法。口服适当放射性标记的餐食后，小肠和结肠转运研究可单独进行，也可与胃排空研究一起进行。希望新发布的这些研究的执行标准以及美国预计将出台的小肠和结肠转运研究的新现行程序术语编码，将增加它们的可及性和应用。
