Peripheral Magnetic Resonance Angiography

Topics in Magnetic Resonance Imaging, 2001
Peripheral vascular disease (PVD) is a common disorder in western society. Reflecting on the risks and costs of contrast arteriography, magnetic resonance angiography is a powerful noninvasive imaging modality for the diagnostic workup of patients with peripheral vascular disease.

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.

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.

Abdominal Magnetic Resonance Angiography

Magnetic Resonance Imaging Clinics of North America, 2020
MR imaging hardware and software improvements have led to new applications for contrast-enhanced and noncontrast-enhanced magnetic resonance angiography in the abdomen and pelvis. Higher magnetic field strength MR imaging scanners have greater signal-to-noise ratio and contrast-to-noise ratio, which is used to improve spatial resolution or temporal ...

Coronary Magnetic Resonance Angiography

Cardiology in Review, 2001
Despite 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

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.

Intracranial Magnetic Resonance Angiography

Cardiovascular and Interventional Radiology, 1992
Intraarterial 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: A review

Academic Radiology, 1998
Summary MR technology continues to advance at a spectacular pace. It is increasingly useful for safe, accurate imaging of vascular anatomy and pathology throughout the body.

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.

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.
