Abstract:
Treatment of cancer involves a multidisciplinary approach consisting of surgery, chemotherapy, molecular targeted therapy and radiation therapy. These therapies work on the tumor cells to result in cell stasis or cell death. The same mechanism can result in toxicity to the normal gastrointestinal tract. Radiation therapy can cause acute and chronic injury. The chronic injury results from involvement of the vascular supply of the gastrointestinal tract and by causing fibrosis. The purpose of this article is to describe the imaging of complications resulting from oncologic treatment in the gastrointestinal system.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
