Figure 3. The MTR and qMT-derived bound pool fraction.

Figure 3.

a. Representative MTR (upper) and qMT-derived f maps (lower) overlaid on the MT-weighted images (50 kHz) of sham (left) and RAS (right) kidneys, b. Box plots show the measured MTR (upper) and f (lower) in the CO, OM, and IM+P of sham and RAS mice. Compared to sham controls, the measured MTR and f in the RAS kidneys rose significantly in all kidney zones. Notably, larger changes in f was observed than those in the MTR across all kidney zones. *P<0.05 vs. Sham; †P<0.05 vs. CO of the same group; ‡P<0.05 vs. OM of the same group. qMT=quantitative magnetization transfer; MTR=magnetization transfer ratio; RAS=renal artery stenosis. CO=cortex; OM=outer medulla; IM+P=inner medulla plus papilla.
