Answer:
The correct answer is: Magnetic Resonance Angiography.
Explanation:
The MRA, abbreviated from Magnetic Resonance Angiography, is a technique used in medicine to help locate abnormalities in the blood vessels, such as aneurysms (weakening of the arteries' walls) and atherosclerotic plaques (produced by cholesterol and a common cause of heart attacks and strokes).
The MRA uses a magnetic field, radio waves, and a computer. Sometimes, doctors may also use contrast material, commonly administered with a small intravenous (IV) catheter in the vein.
