Core Tip
Core tip: In the modern era of adaptive radiotherapy, it is crucial to understand how different imaging techniques interact and complement each other for application in cancer care. The quantitative imaging metrics, apparent diffusion coefficient and standardized uptake value, play a significant role in understanding the efficacy of the radiotherapy treatment. Tumor cellularity and glucose metabolism were investigated before, during, and after radiotherapy in human papillomavirus negative head and neck squamous cell carcinoma patients using the diffusion-weighted magnetic resonance imaging and 18F-labeled fluorodeoxyglucose positron emission tomography/computed tomography imaging techniques.
