Figure 2b:

(a) Typical coronal ADC maps of the kidneys in a mouse in group 1 before UUO (day 0) and on days 3 and 7 after UUO. ADCs were averaged over three orthogonal directions to eliminate possible anisotropic effect. (b) Graph illustrates changes in renal cortex ADC, which decreased in a time-dependent manner on the UUO side (five mice in group 1). All data are expressed as percentage changes, in means ± standard deviations, relative to baseline value, with P = .05 (*) and P < .01 (**) for comparisons of UUO and contralateral sides at unpaired two-tailed Student t testing.
