Radionuclide esophageal and intestinal transit scintigraphy in patients undergoing radiation therapy

Radiation esophagitis and enteritis are common and significant side effects of radiation therapy. Non-invasive assessment of functional and/or anatomic changes responsible for the symptoms produced by radiation esophagitis and enteritis has been unsatisfactory. This paper demonstrates the value of radionuclide esophageal and intestinal transit scintigraphy in patients undergoing mediastinal or abdominal radiation.
