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

Seminars in Roentgenology, 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.

Instrumentation for Magnetic Resonance Angiography

Cardiovascular and Interventional Radiology, 1992
Magnetic resonance angiography (MRA) places high demands on instrumentation capabilities. Magnetic gradient strength capabilities, main magnetic field strength and homogeneity, and eddy current compensation all play a role in determining the quality of the flow studies.

Multiecho magnetic resonance angiography

Magnetic Resonance in Medicine, 1987
AbstractSeveral pulse sequences which generate projected MR angiograms are presented. These pulse sequences exploit multiple‐gradient refocused echoes to obtain several independent angiograms, which can be combined or separately analyzed to provide more information than an individual angiogram. For example, a series of angiograms, each with a different

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 ...

Magnetic Resonance Angiography in Prostatodynia

European Urology, 1995
Three-dimensional magnetic resonance venography (3D MRV) of the prostate and the pelvic cavity was demonstrated in 8 normal subjects and 12 patients with prostatodynia. In all normal subjects and patients, 3D MRV images were successfully obtained. The deep dorsal vein of the penis sends major branches into the anterior and lateral capsular veins as ...

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.

Stereotactic Magnetic Resonance Angiography

Stereotactic and Functional Neurosurgery, 1992
Visualization of the surgical trajectory with respect to the cerebral vasculature may enhance the safety of some stereotactic neurosurgical procedures. Traditional stereotactic angiography is tedious and, being an invasive procedure, poses some risk to the patient.

Magnetic Resonance Coronary Angiography

The American Heart Hospital Journal, 2003
Coronary artery disease is the leading cause of death in the United States. Catheter-based x-ray angiography is the current standard for diagnosis of coronary artery disease. Coronary angiography using cardiovascular magnetic resonance is a rapidly evolving technique that can noninvasively image the coronary arteries. The authors will discuss the basic
