Resistive and pulsatility index of renal artery and aorta of dogs.

Variable	Control (n = 20)	PDH (n = 20)
Aorta RI	0.92 ± 0.04	0.91 ± 0.07
Aorta PI	3.13 ± 0.64	2.87 ± 0.50
Renal RI	0.65 ± 0.03	0.69 ± 0.06∗
Renal PI	1.20 ± 0.12	1.39 ± 0.27∗
Increased renal RI (%)	1/20 (5%)	10/20 (50%)∗
Increased renal PI (%)	0/20 (0%)	7/20 (35%)∗

Data are presented as mean ± SD or n (%). PDH, pituitary-dependent hyperadrenocorticism; PI, pulsatility index; RI, resistive index.

  ^∗ P < 0.05 relative to control.
