Magnetic resonance angiography
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]
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.

Ghost magnetic resonance angiography [PDF]
AbstractTraditional methods for magnetic resonance angiography (MRA) involve the radiofrequency excitation of vascular spins within a selected region of tissue, followed by gradient localization and imaging of those spins within that same region.
