Diagram illustrates study design and assignment of mice to study groups. Five mice in group 1 were examined with longitudinal diffusion-weighted (DW) imaging (solid arrows) before UUO (day 0) and on days 3 and 7 after UUO. For histopathologic correlation at each diffusion-weighted imaging time point (dotted arrows), an additional group of mice were examined on days 0 (group 2, four mice) and 3 (group 3, five mice).
