How is a renal angiogram performed?

Dye injected: A tube is placed into the aorta and by x-ray guidance is moved to the area of the renal artery. Dye is then injected and picures are taken to see if the artery is normal or blocked.

Invasive examination: A renal angiogram is a minimally invasive examination. The doctor will likely enter the artery located in the right groin initially with a small needle and then change that for a plastic tube. A catheter (small plastic tube) is then advanced into the aorta and then selectively into the renal artery. A small amount of dye is then injected. Us, ct or MRI usually done before this test.
