Cerebral magnetic resonance angiography
Neurological Research, 1992Magnetic 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.

Coronary Magnetic Resonance Angiography
Cardiology in Review, 2001Despite advances in both prevention and treatment, cardiovascular disease remains the leading cause of morbidity and mortality in the United States. The current gold standard for the diagnosis of coronary artery disease is the x-ray coronary angiogram, which is both costly and associated with a small risk of morbidity. More than 1 million Americans are

Intracranial Magnetic Resonance Angiography
Cardiovascular and Interventional Radiology, 1992Intraarterial angiography remains the "gold standard" for the evaluation of the intracranial vasculature, but it carries with it the risks of local vascular damage, systemic reactions, transient neurologic deficits, permanent neurologic compromise, and even death.

Magnetic resonance angiography.
The British Journal of Radiology, 1997Magnetic 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 pulmonary angiography
Coronary Artery Disease, 1999Just 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.

Cardiothoracic Magnetic Resonance Angiography
Current Problems in Diagnostic RadiologyCatheter-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 Angiography
2001Magnetic 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.

Magnetic Resonance Angiography
2013The 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.
