Magnetic resonance angiography
Medical Journal of Australia, 1993 To outline the physical principles of magnetic resonance angiography (MRA), major current MRA techniques, clinical indications and some of the limitations of MRA. The rapidly changing nature of MRA techniques is stressed.The MRA literature for the last eight years is reviewed with particular attention to the changing clinical role of MRA.

Pulmonary magnetic resonance angiography [PDF]
Journal of Magnetic Resonance Imaging, 1999 Early attempts to image the pulmonary vasculature with spin-echo magnetic resonance (MR) imaging were hampered by severe image degradation related to respiratory and cardiac pulsation artifact, susceptibility at interfaces between lung parenchyma and vessel wall, and poor contrast between flowing blood and intravascular filling defects of emboli.

Magnetic resonance angiography signal intensity as a marker of hemodynamic impairment in intracranial arterial stenosis. [PDF]
, 2013 BackgroundIntracranial arterial stenosis (ICAS) is the predominant cause of ischemic stroke and transient ischemic attack in Asia. Change of signal intensities (SI) across an ICAS on magnetic resonance angiography (MRA) may reflect its hemodynamic ...

Magnetic Resonance Angiography [PDF]
Current Protocols in Magnetic Resonance Imaging, 2002 AbstractThe “flow compensation” of moving spins is necessary to visualize blood in MR imaging. This unit discusses the effects of blood flow in detail, particularly in regard to obtaining an accurate measurement of the blood vessel lumen (the interior dimensions of the vessel).
