Coronary Magnetic Resonance Angiography
Herz, 2003Coronary 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).

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.

Magnetic resonance angiography
Seminars in Vascular Surgery, 2004MRA 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.

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.

Multiecho magnetic resonance angiography
Magnetic Resonance in Medicine, 1987AbstractSeveral 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

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.

Instrumentation for Magnetic Resonance Angiography
Cardiovascular and Interventional Radiology, 1992Magnetic 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.

Magnetic Resonance Angiography in Prostatodynia
European Urology, 1995Three-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 ...

Magnetic resonance coronary angiography
Current Cardiology Reports, 2003Magnetic resonance coronary angiography (MRCA) has witnessed tremendous technical advances over the past decade. Although high-quality images of the coronary arteries have been demonstrated, this imaging modality is not performed routinely today. The fundamental properties of the coronary arteries deterring noninvasive imaging are well known.

Coronary magnetic resonance angiography
Journal of Magnetic Resonance Imaging, 2007AbstractCoronary magnetic resonance angiography (MRA) is a powerful noninvasive technique with high soft‐tissue contrast for the visualization of the coronary anatomy without X‐ray exposure. Due to the small dimensions and tortuous nature of the coronary arteries, a high spatial resolution and sufficient volumetric coverage have to be obtained. However,
