Detecting malignant lymph nodes in the neck remains a challenge such that most patients still have to consider aggressive treatment including nodal dissection. In this study, we used positron emission tomography with 18F-fluorodeoxyglucose (18F-FDG PET), dynamic contrast enhanced magnetic resonance imaging (DCE-MRI), and diffusion weighted imaging (DWI) to assess head and neck cancer cases and consider the feasibility of using all three imaging methods in synergy to assess the regional lymph nodes.
