Magnetic resonance angiography.

The British Journal of Radiology, 1997
Magnetic resonance angiography (MRA) permits the non-invasive visualization of blood flow through the effects of moving spins on the magnetic resonance signal. MRA techniques can be divided into two main classifications depending upon the primary effect responsible for contrast in the image.

Magnetic Resonance Angiography

IEEE Transactions on Medical Imaging, 1986
This paper describes several methods for magnetic resonance angiography that create projection images based solely on flowing blood. To both remove static tissue from the image and generate signals from blood, two classes of methods considered are temporal subtraction and cancelling excitation.

Magnetic resonance angiography

Current Opinion in Cardiology, 1998
Since the emergence of magnetic resonance (MR) imaging, its clinical applications have seen a logarithmic growth. The advantage of MR imaging is that it offers a vast amount of important clinical information with minimal risk to the patient, and promises to reduce the need for angiographic studies with their attendant morbidity and mortality.

Coronary Magnetic Resonance Angiography

Herz, 2003
Coronary magnetic resonance angiography (CMRA) is a technique in clinical evolution. Current clinical applications include assessment for coronary anomalies, aneurysms, bypass graft patency, and, in experienced centers, the exclusion of proximal and multivessel coronary artery disease (CAD).

Magnetic resonance angiography

Seminars in Vascular Surgery, 2004
MRA and MRI have become increasingly important diagnostic modalities in vascular surgery. The ability to obtain cross-sectional and angiographic images by these noninvasive and non-nephrotoxic modalities represents one of the most significant advances in vascular surgery over the past decade.
