Summary
Magnetic Resonance Angiography (MRA) is an examination similar to Magnetic Resonance Imaging
(MRI) which uses a magnetic field and a contrast medium when needed to visualize blood flow
in the arterial vessels throughout the body.
Gadodiamide, a contrast medium, is already approved and is used to image blood vessels by
directly injecting it into the vein, but this procedure has not been formally tested to image
the renal artery vessels using MR.
The study is designed to determine the presence or absence of a relevant stenosis (ie greater
than/equal to 50%) or occlusion in renal arteries. Intra-arterial Digital Subtraction
Angiography will be used as the standard of truth.
