Ferumoxytol-enhanced magnetic resonance angiography for endovascular aortic repair surveillance in a patient after renal transplant [PDF]
Endovascular aneurysm repair requires lifelong imaging surveillance, typically with contrast-enhanced computed tomography imaging. This poses risks to patients with end-stage renal disease.

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.

Magnetic Resonance Angiography [PDF]
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).
