Magnetic resonance angiography

open access: yesMedical 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]

open access: yesEuropean Radiology, 1999
In the past few years magnetic resonance angiography (MRA) of the pulmonary vasculature has advanced from a research tool to a clinically relevant imaging modality. Early 2D phase-contrast and time-of-flight (TOF) sequences without the use of contrast agents were time-consuming and limited by considerable imaging and motion artifacts.

Rationale and design of the Clinical Evaluation of Magnetic Resonance Imaging in Coronary heart disease 2 trial (CE-MARC 2): a prospective, multicenter, randomized trial of diagnostic strategies in suspected coronary heart disease [PDF]

open access: yes, 2015
Background: A number of investigative strategies exist for the diagnosis of coronary heart disease (CHD). Despite the widespread availability of noninvasive imaging, invasive angiography is commonly used early in the diagnostic pathway.

Magnetic resonance angiography signal intensity as a marker of hemodynamic impairment in intracranial arterial stenosis. [PDF]

open access: yes, 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 ...
