Table 1.
IVIM parameters estimated on the cortex and medulla for all subjects. The values were computed from manually segmented masks of the medulla and cortex of the kidneys. Both the IVIM and DTI parameters of the subjects are in concordance with the values reported in the literature for healthy subjects.
