METHODS Positron-emission tomography (PET)/computed tomography (CT) examinations of patients with head and neck squamous cell carcinoma (SCC) and non-squamous cell carcinoma (non-SCC) tumors with 52 patients reviewed from 2007 to 2019 retrospectively. MTV and SUVmax values of primary tumor were measured in PET/CT and both groups were statistically compared. RESULTS The median SUVmax value was 17.88 (3-52) and MTV was 5.40 (0-329). No significant difference was established between the groups in terms of age, gender and MTV (p=0.948, p=0.166 and p=0.189) respectively. SUVmax value in SCC group was significantly higher (p=0.003) than the non-SCC group. CONCLUSION Head and neck squamous cell carcinomas (HNSCC) have higher SUVmax values than non SCC tumors. No significant difference was established between the groups in terms of MTV.Head and neck cancermetabolic tumor volumepositron emission tomographysquamous cell carci-nomastandardized uptake valueArticleWOS:000625220200004
