The accurate interpretation of gastrointestinal transit studies often requires quantification of the data. Particles radiolabelled with indium-111 have been monitored using a gamma camera, during transit through the stomach and the small and large intestines of normal subjects. The count rates measured from either anterior or posterior images alone showed considerable variations, and depended on the site of the tracer within the gut. The geometric mean values of corresponding anterior and posterior count rates remained almost constant throughout each study.
胃肠道转运研究的准确解读通常需要对数据进行量化。在用铟 - 111进行放射性标记的颗粒通过正常受试者的胃、小肠和大肠的过程中，使用γ相机对其进行了监测。仅从前部或后部图像测得的计数率显示出相当大的差异，并且取决于示踪剂在肠道内的位置。在每项研究中，相应的前部和后部计数率的几何平均值几乎保持恒定。
