From: Effects of iodinated contrast agents on renal oxygenation level determined by blood oxygenation level dependent magnetic resonance imaging in rabbit models of type 1 and type 2 diabetic nephropathy

Figure 2

BOLD images obtained using 400 mg I/mL of contrast agent. (A) Control group. (B) Type 2 diabetic nephropathy group injected with saline. (C–F) Type 2 diabetic nephropathy group injected with 400 mg I/mL of contrast agent (C, 1 h; D, 24 h; E, 48 h; F, 72 h). Higher intensities on the R2* map indicate lower oxygenation of the underlying tissue. The intensity of the outer medulla of the diabetic kidney was greater than that in the cortex and inner medulla, which implies lower oxygenation of the outer medulla than the other regions.
