The SUV(max) ratio represents an accurate imaging biomarker for differentiating tonsillar SCC from physiologic (18)F-FDG uptake.

Cystic and cystic-appearing lesions of the mandible are commonly noted on head and neck imaging and present a diagnostic dilemma for the radiologist. This article aims to help outline the differential diagnosis for cystic mandibular lesions, outline the key imaging features, and suggest recommendations for further imaging and/or intervention when required.

FDG uptake, as measured by corrected SUV(max), may be a predictive imaging biomarker for DFS and overall survival in patients with head-and-neck non-SCC.
