Radiation-Induced Esophagitis on FDG PET Imaging

Abstract
Whole-body fluorodeoxyglucose positron emission tomographic (FDG PET) imaging is now being used for staging and restaging patients with a variety of cancers. Benign and inflammatory disorders have been reported to take up FDG, and it is important to recognize these on PET images for appropriate interpretation. The authors present a 76-year-old man who was treated with radiation for poorly differentiated nonsmall cell lung cancer and whose posttherapy PET images showed FDG uptake in the region of radiation-induced esophagitis.
