From Paper: “MR-linac (MRL)-based radiotherapy allows daily anatomical and physiological imaging for adaptive treatment. Apparent diffusion coefficient (ADC) derived from diffusion-weighted imaging (DWI) is a quantitative biomarker correlated with tumor cellularity and response. Verifying ADC repeatability and reproducibility across centers is key for multi-center physiological adaptive radiotherapy trials on low-field MRLs.”
