PET/CT in Oral Cavity and Oropharyngeal Cancer in Post Therapy Setting
Kositwattanarerk A 
F-FDG PET/CT is an immerging tool for follow-up a head and neck cancer patients. Accurate PET/CT interpretation
in a post therapy setting is crucial for proper management. However, there are many limitations in post therapy settings. For
example, variable degree of normal physiologic uptake is noted. Physiologic processes cannot be identified by symmetrical
FDG uptake in a post therapy setting. The present article demonstrates case series including asymmetrical, abnormal, or
unusual patterns of FDG uptake within the oral cavity and oropharyngeal structures in both benign and malignant conditions.
