MR angiography (MRA) uses a powerful magnetic field, radio waves and a computer to evaluate blood vessels and help identify abnormalities. This exam does not use radiation and may require an injection of contrast material.
Abstract. Magnetic resonance angiography (MRA) has been used to image abdominal vessels less frequently than renal arteries. Until the use of fast contrast-enhanced (CE) techniques, an important limitation was the acquisition time of phase-contrast or time-of-flight imaging and, consequently, the creation of motion artifacts.

Other applications such as vascular tumors and arterial or venous occlusive disease are under investigation. AB - The use of MR angiography to evaluate spinal vessels is in an early stage of development. BACKGROUND AND PURPOSE: The cause of posterior reversible encephalopathy syndrome (PRES) is unknown.
