Figure 2. Renal oxygenation by blood oxygenation level dependent MRI.

Figure 2.

(a) Representative kidney R2* maps at baseline, graded ischemia, and recovery. Increasing intensity and extent of the red color suggests development of hypoxia. (b) R2* measured in the renal cortex and medulla at all time points. *P<0.05 vs. Baseline, #P<0.05 vs. 50% RAS, $P<0.05 vs. 75% RAS, &P<0.05 vs. 100% RAS.
