Magnetic resonance angiography–also called a magnetic resonance angiogram or MRA–is a type of MRI that looks specifically at the body’s blood vessels. Unlike a traditional angiogram, which requires inserting a catheter into the body, magnetic resonance angiography is a far less invasive and less painful test.
Magnetic resonance angiography (MRA) is an imaging test that shows your blood vessels and blood flow. An MRA can detect narrowing or blockages in your arteries in a noninvasive way.
An MRA of the head is done to look at the blood vessels leading to the brain to check for a bulge (aneurysm), a clot, or a narrowing (stenosis) because of plaque.
Both an MRI (magnetic resonance imaging) and MRA (magnetic resonance angiography) are noninvasive and painless diagnostic tools used to view tissues, bones, or organs inside the body.
MRA of the Brain: Exam Description. Your doctor has ordered a MRA (Magnetic Resonance Angiography) of your brain. MRA uses a magnetic field, radio waves and a computer to create images of soft tissues, bones, and internal body structures. An MRA of the brain is used to produce two three-dimensional images of the blood vessels.
The MRA procedure is used to identify abnormalities in your body, including brain aneurysms and blockages in the blood vessels that could lead to stroke or a heart attack. Usually, the doctor orders an MRA of the head to check the blood vessels leading to the brain.
In magnetic resonance angiography (MRA), a powerful magnetic field, radio frequency waves and a computer are used to evaluate blood vessels and help identify abnormalities. This exam, like all MR-based exams, does not use radiation. An MRA exam may or may not use contrast material.
MRA of the brain is used to assess abnormalities in the arterial blood supply system of the brain. The most frequently employed method for assessing the brain’s arterial blood supply system is the three-dimensional (3D) time-of-flight (TOF) MRA. This technique offers advantages such as improved signal-to-noise ratio and shorter imaging times.
MRA is a type of MRI that looks specifically at blood vessels in the body. MRA is often used to examine the blood vessels in the brain, neck, abdomen, heart, chest, arms and legs.
A brain MRI (magnetic resonance imaging) scan, also called a head MRI, is a painless procedure that produces very clear images of the structures inside of your head — mainly, your brain. MRI uses a large magnet, radio waves and a computer to produce these detailed images.
