1y FS Hound cross. Images a–c are ordered from cranial to caudal. The renal artery is smaller than the vein and arises from the lateral
aspect of the aorta (a: arrowhead). The renal vein is larger, arising from the caudal vena cava (a: asterisk). The ureters can be seen
exiting the renal pelvis (a: arrows) and coursing ventrolateral to the aorta and caudal vena cava (b: arrows) in the pyelogram phase.
The ureters terminate near the bladder trigone (c: arrows) and cascades of contrast‐enhanced urine stream to the dependent bladder (c).
The course of the ureters can be seen through the retroperitoneal space on a ventrodorsal MIP projection (d).

14y MC Norwegian Elkhound. The kidneys
are hyperintense to spleen on T1 images
and isointense on T2 images. The renal
artery (b: arrowhead) and vein (b: asterisk)
are best seen on the dorsal plane images.
