Volumetric comparison of positron emission tomography/computed tomography using 4′-[methyl-11C]-thiothymidine with 2-deoxy-2-18F-fluoro-D-glucose in patients with advanced head and neck squamous cell carcinoma

ObjectiveWe prospectively compared the diagnostic value of PET/computed tomography (CT) findings using the tracers 4′-[methyl-11C]-thiothymidine (11C-4DST) and 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG) in patients with head and neck squamous cell carcinoma (HNSCC).Patients and methodsThirty-eight pat
