It uses MRI to provide excellent depiction of the arteries to exclude an aneurysm, arteriovenous malformation, complete blockage or significant narrowing of arteries
MR angiography is an MRI, which uses magnetic fields rather than radiation, designed to look specifically at your blood vessels. It is generally used to look for any narrowings in vessels, aneurysms (regions that are abnormally large), or damage to the vessels such as dissections, where part of the lining of the artery is torn. Hope this helps!
It shows the arteries and veins in your body.
MR angiography is an MRI which takes advantage of flowing blood to see what your vessels look like. It may be performed with or without intravenous administration of Gadolinium based contrast.
Advantages over CT angiography is no need for Iodinated contrast and MRA can determine direction of blood flow. Disadavantages include going into MR machine which some people cannot tolerate and decreased accuracy do to artifacts.
