Detailed explanation-1: -Magnetic resonance angiography (MRA) denotes a unique option for the evaluation of peripheral vasculature due to its noninvasive nature, lack of ionizing radiation exposure, potential for non-contrast examination, and ability for generating volumetric representations that showcase vascular pathology.
Detailed explanation-2: -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. MRA is primarily used to detect narrowing of the arteries and to rule out aneurysms.
Detailed explanation-3: -The reported specificity of MR angiography (MRA) for carotid artery stenosis has typically included both clinically normal and significantly narrowed carotid arteries, leading to results appropriate for use as a screening test.
Detailed explanation-4: -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. You can have a non-enhanced MRA or a contrast-enhanced MRA.
