The display of blood vessels known as MR angiography is an accurate, non-invasive means of obtaining information about arteries of the head, neck and body.

Using magnetic field and radio wave energy pulses, the MRA provides information that X-rays, CT scans or ultrasounds can’t always obtain. MRA exams are most often used on your neck, legs, kidneys and brain to gather information about the condition of the blood vessel walls and blood flow. They also can be used to search for aneurysms, calcium deposits and clots within the blood vessels. Sometimes, a contrast dye is used to provide better definition of the blood vessels in the scan’s images. Only the area of the body being studies will be placed inside the MRI. Exams range from 30 to 90 minutes.
