How is an intravenous pyelogram actually performed?

By injecting dye: When a contrast material is injected into a vein in the patient's arm, it travels through the blood stream and collects in the kidneys and urinary tract, turning these areas bright white on the x-ray images. An ivp allows the radiologist to view and assess the anatomy and function of the kidneys, ureters and the bladder.

Ivp: Iodinated contrast ( x-ray dye) is injected into a vein via an iv. You then wait until your kidneys start to clear it then take x rays at different intervals as it shows up in your kidney and urinary collecting system.
