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. We review

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.

Computed Tomography Angiography and Magnetic Resonance Angiography of Congenital Anomalies of Pulmonary Veins.

Journal of computer assisted tomography, 2019
We aimed to review computed tomography and magnetic resonance angiography of congenital anomalies of pulmonary veins. Total anomalous pulmonary venous return shows all pulmonary veins drain abnormally in another site rather than left atrium.

Surface and interfacial engineering of iron oxide nanoplates for highly efficient magnetic resonance angiography.

ACS Nano, 2015
Magnetic resonance angiography using gadolinium-based molecular contrast agents suffers from short diagnostic window, relatively low resolution and risk of toxicity. Taking into account the chemical exchange between metal centers and surrounding protons,

Computed tomography angiography and magnetic resonance angiography imaging of the mesenteric vasculature.

Techniques in Vascular and Interventional Radiology, 2015
Computed tomography angiography (CTA) and magnetic resonance angiography (MRA) are highly accurate cross-sectional vascular imaging modalities that have almost completely replaced diagnostic catheter angiography for the evaluation of the mesenteric ...

Magnetic Resonance Angiography [PDF]

, 2001
Magnetic resonance angiography (MRA) has become an important technique in vascular diseases. Although conventional digital subtraction angiography (DSA) still is the gold standard for the evaluation of vascular pathology, MRA provides more than just anatomic information. In all MRA techniques, image contrast is the result of blood motion.
