MR angiography (MRA) is an MRI exam of the blood vessels. MRA can detect, diagnose, and aid the treatment of heart disorders, stroke, and blood vessel diseases. MRA can take detailed pictures of blood vessels without using any contrast material, although a contrast usually is given to make the MRI pictures even more clear. How does the exam work?
