Diffusion-derived parameter maps of an unaffected kidney (a-d), a kidney with renal cell carcinoma (e-h), and a kidney with oncocytoma (i-l). First row (e, j): gross appearance of the whole kidney or tumour after nephrectomy, (a, f, k): anatomical reference (after processing) (T2-TSE), second row (b, g, l): the unweighted image of the diffusion scan after motion correction and image registration (DWI-b0), third row (c, h, m): a merge of the fraction maps from the tri-exponential fit red = ffast, blue = finterm, green = fslow (1- finterm - ffast), fourth row (d, i, n): diffusion coefficient from the tri-exponential fit, (Dtri)
