ADC maps of an axial MRI slice showing active tumour using monoexponential model for 0–1000 (A), 50–1000 (B), 100–1000 (C), 250–1000 (D), 500–1000 (E), 250, 500 and 1000 (F), 250, 650 and 1000 (G), 250, 800 and 1000 (H), 250 and 800 (I), 250 and 1000 µs/µm2 b-value sets (J), and using IVIM model for the set of all eight b-values- 0, 50, 100, 250, 500, 650, 800 and 1000 µs/µm2 (K), and b 0 mage (no diffusion weighting) (L). High intra-slice CV within the tumour is observed n panels (E) and (I).
