An MRA is an imaging test that lets your doctor see inside yourbloodvessels -- yourarteriesand veins. MRA stands for magnetic resonance angiogram or magnetic resonance angiography. It’s a type of magnetic resonance imaging, or MRI. Instead of using radiation, like with X-rays and computed to...
Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging to demonstrate blood vessels, looking for evidence of stenosis, occlusion, or aneurysm formation. Demonstration of abnormalities in the vena cava in patients with large renal cancers is a particular ...

Magnetic resonance angiography (MRA) of head and neck showing the appearance of the medial limb of the left vertebral artery (mVA) as a continuation of the vertebral artery over the first part of the left subclavian artery (LS); presented cerebral vessels are the middle cerebral arteries (MCA...
Magnetic resonance angiography (MRA) has virtually replaced diagnostic conventional X-ray angiography and has become the primary imaging tool for the evaluation of the diseases of the aorta and branches for many indications (1–13). Development of faster magnetic resonance imaging (MRI) scanners with...
"Most previous investigations of MRA had fewer than 20 patients with pulmonary embolism," say the researchers.. 2010 Nature Publishing GroupJoana OsorioOsorio J (2010) Molecular imaging: magnetic resonance angiography in pulmonary embolism diagnosis. Nat Rev Cardiol 7(6):302. : 10.1038/nr...
Non-invasive imaging of cardiovascular disease in pediatric subjects has been an elusive and much anticipated development for many years. Magnetic resonance angiography (MRA) has now been established in many institutions as an important diagnostic method for evaluating vascular disease in adults. However...
