CT MRI Varicose Veins Breast MRI PET Lincoln Nebraska I have heard of MRI, but what is MRA?
Magnetic resonance angiography (MRA) uses a magnetic field and pulses of radio wave energy to provide pictures of blood vessels inside the body. In many cases, MRA can provide information that cannot be obtained from an X-ray, ultrasound, or CT scan. MRA can detect problems with the blood vessels that may be causing reduced blood flow. With MRA, both the blood flow and the condition of the blood vessel walls can be seen. The test is often used to evaluate the blood vessels leading to the brain, kidneys, and legs. During MRA, the area of the body being studied is positioned inside an MRI machine. Contrast material is often used during MRA to make blood vessels show up more clearly. Douglas Winjum, M.D.
