•Mean ADC values were reproducible with wCVs between 13.7% and 24.4%•Mean ADC values differed between 93 ·10-6 mm2/s 6.4% for target volumes and 254 ·10-6 mm2/s 24.3% for parotid glands between diagnostic scanner and MR-Linac.•Intraclass correlation coefficient was better for target volumes than gla...
