    The MRA scan is a form of an MRI and is performed with the same machine. The only difference is that the MRA takes more detailed images of the blood vessels than the organs or tissue surrounding them.

  3. An MRI scan is different from a CT scan or an X-ray in that it doesn’t use radiation to produce images. An MRI scan combines images to create a 3-D picture of your internal structures, so it’s ...

    en.wikipedia.org/wiki/Magnetic_resonance_angiography

    Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.

    Magnetic resonance angiography (MRA) generates pictures of the arteries to evaluate them for stenosis (abnormal narrowing) or aneurysms (vessel wall dilatations, at risk of rupture). MRA is often used to evaluate the arteries of the neck and brain, the thoracic and abdominal aorta, the renal arteries, and the legs (called a "run-off").

    B030ZZZ. ICD-9-CM. 88.91. OPS-301 code. 3-800, 3-820. Magnetic resonance imaging of the brain uses magnetic resonance imaging (MRI) to produce high quality two-dimensional or three-dimensional images of the brain and brainstem as well as the cerebellum without the use of ionizing radiation (X-rays) or radioactive tracers.
