Data are medians with interquartile range in parentheses. ^*f, α, and MK have no units, ^†p value from statistical comparison between benign and malignant lesions, between ccRCC and non-ccRCC, between low-grade and high-grade ccRCC, respectively, by using Mann-Whitney U test. ADC = apparent diffusion coefficient, ccRCC = clear cell renal cell carcinoma, DDC = distributed diffusion coefficient, D_f = fast diffusion coefficient, D_s = slow diffusion coefficient, f = fraction of fast diffusion, MD = mean diffusivity, MK = mean kurtosis, α = anomalous exponent term
