Renal arteries are the arteries that supply blood to the kidneys. A renal angiogram is used to find narrow or blocked renal arteries. During an angiogram, an x-ray solution is injected into one or several arteries, and x-rays are used to capture images of blood flow.
A peripheral angiogram is an x-ray procedure used in the cardiac cath lab. A peripheral angiogram detects narrow or blocked peripheral arteries, the arteries in your legs. An x-ray solution is injected into an artery or arteries and an x-ray is used to capture images of blood flow through the arteries.
