Abstract:
This pictorial essay depicts normal appearances, complications, and findings of residual and/or recurrent disease on fluorodeoxyglucose positron emission tomography/computed tomography (18F- FDG PET/CT) studies in the postsurgical setting. Reading and reporting 18F- FDG PET/CT in the postoperative scenario is demanding due to the multiple false positives seen during this period. This article which contains two parts will familiarize the readers with the normal appearance and pitfalls seen in 18F- FDG PET/CT studies during the postoperative period so as to avoid misinterpretations. This pictorial will discuss 18F- FDG PET/CT in the postoperative scenario in head and neck cancers.
