Call 911 or seek emergency treatment if you have any of the following symptoms that might indicate a pulmonary blockage: Pulmonary magnetic resonance angiography (PMRA) does not require exposure ...

Multimodal imaging with exercise duplex ultrasonography and magnetic resonance angiogram confirmed the presence of flow-limiting stenoses in the left external iliac artery consistent with a diagnosis ...

A multicenter study by the PIOPED III Investigators has shown that magnetic resonance angiography (MRA) can be used to detect pulmonary embolism. The proportion of technically inadequate images ...

MRA (magnetic resonance angiography) is used to evaluate blood vessels in the body. Unlike catheter-based and CT angiograms, MRA uses a strong magnet, radiofrequencies and a computer instead of X-rays ...

We compared two-dimensional time-of-flight magnetic resonance angiography (MRA) and duplex ultrasonography with arteriography for the detection of 70% to 99% stenoses at the carotid artery bifurcation ...

This study was designed to elucidate the outcome and prognosis of adults diagnosed with VBD by magnetic resonance angiography (MRA) and to ascertain if these outcomes were independent of known ...

revealed multiple acute infarcts in the cerebellar hemispheres bilaterally and magnetic resonance angiogram (MRA) demonstrated stenosis of the bilateral carotid arteries, vertebral arteries ...

Special applications of magnetic resonance imaging include magnetic resonance angiography (MRA) and magnetic resonance venography (MRV). Positron emission tomography (PET) is a nuclear medicine ...

Objective To validate AVM hemodynamics assessed by DSA using quantitative magnetic resonance angiography (QMRA). Materials and methods Patients seen at our institution between 2007 and 2016 with a ...

Magnetic resonance angiography (MRA) is a noninvasive imaging test that uses a magnetic field and a computer to produce detailed pictures of the major blood vessels of the body. It can be used to ...
