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.

An MRA is a noninvasive alternative to a traditional angiogram. It uses an MRI to scan your blood vessels. An MRA can help diagnose a condition like blood clots.

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.

2021年12月13日 · Magnetic resonance angiography (MRA) is a test that helps physicians and radiologists take the blood vessels’ image to diagnose or rule out certain diseases or conditions. In MRA, radio frequency waves and a computer system create detailed images of your body’s major blood vessels, mainly the artery.

2018年8月23日 · Both MRAs and MRIs are used to view internal parts of the body. MRIs are used for brain abnormalities, joint injuries, and various other abnormalities while MRAs can be ordered for: MRIs and MRAs...

2024年9月30日 · Peering inside the brain’s intricate network of blood vessels, MRA (Magnetic Resonance Angiography) emerges as a powerful, non-invasive diagnostic tool that revolutionizes the detection and management of cerebrovascular conditions.

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 stands for magnetic resonance angiography. 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.
