MR angiography, or cardiac MRI uses a magnetic resonance imaging technology to see blood vessels inside the body. The test is typically used to evaluate the blood vessels leading to the brain, kidneys and legs. In many cases, the exam can provide diagnostic information that cannot be done by using other modalities. MRA can track problems in the blood vessels that may block blood flow. With MRA, blood flow and the blood vessel walls can be seen on screen. The exam is helpful in detecting an aneurysm and narrowing or stenosis of blood vessels lead to the lungs, kidneys or legs.
