PORTAL MAGNETIC RESONANCE ANGIOGRAPHY

Magnetic Resonance Imaging Clinics of North America, 1993
MR angiography has shown definite clinical use in the portal venous system. Methods have been developed for noninvasive assessment of portal venous anatomy and blood flow using a variety of techniques. Time-of-flight techniques for portal angiography and both time-of-flight and phase-contrast techniques for flow measurement are reviewed.

Cerebral magnetic resonance angiography

Neurological Research, 1992
Magnetic resonance angiography (MRA) is an accurate non-invasive tool for imaging the cerebral vessels. It provides morphologic information about the cerebral vessels relying on blood flow as the physical basis for generating contrast between stationary tissues and moving spins.

MAGNETIC RESONANCE ANGIOGRAPHY OF THE ABDOMEN

Gastroenterology Clinics of North America, 1995
The applications of abdominal MR angiography have been slow as compared with its applications in the head and neck mainly because of greater technical difficulties in dealing with respiratory motion and the use of the body coil, which has a poorer signal-to-noise ratio than head or surface coils.

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.

Cardiothoracic Magnetic Resonance Angiography

Current Problems in Diagnostic Radiology
Catheter-based angiography is regarded as the clinical reference imaging technique for vessel imaging; however, it is invasive and is currently used for intervention or physiologic measurements. Contrast enhanced magnetic resonance angiography (MRA) with gadolinium-based contrast agents can be performed as a three-dimensional (3D) MRA or as a time ...

Magnetic resonance pulmonary angiography

Coronary Artery Disease, 1999
Just recently, use of magnetic resonance imaging for thoracic investigations has become increasingly appealing. This resurgence has been triggered by the enormous improvements in image quality with the development of scanners with faster data-acquisition capabilities and the routine use of contrast agents.

Magnetic Resonance Angiography

2013
The clinical use of magnetic resonance angiography (MRA) has rapidly expanded as technological advances in both hardware and imaging techniques overcome previous limitations. This is particularly true for imaging of patients with congenital heart disease (CHD), who are often younger and frequently require continued, lifelong imaging follow-up.
