What is an ultrasound and renal arteriogram?
A renal ultrasound is an x-ray test that shows the size, number, position and structure of the kidneys. A renal arteriogram is an x-ray test that shows the number, size and location of the renal arteries (vessels that supply blood to the kidneys). A dye is injected into a large artery in the groin. This dye flows into the renal arteries so that they can be seen by x-ray.
