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

Renal artery stenosis (RAS) is one of the most common causes of severe hypertension (approximately 1-5% of all patients with hypertension). Presently, there is no universally accepted screening test for RAS.

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 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.

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.

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 Angiography Techniques
Investigative Radiology, 1992After a radio frequency pulse, the decay of the magnetic resonance (MR) signal is described by two relaxation processes, T1 and T2. T1 describes the rate at which the magnetization realigns itself along the external magnetic field direction (ML), and T2 describes the rate of decay of the magnetization component along the transverse axis (MT).

Stereotactic Magnetic Resonance Angiography
Stereotactic and Functional Neurosurgery, 1992Visualization 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 angiography for the evaluation of vascular injury in knee dislocations.
The journal of knee surgery, 2010Knee dislocations can cause extensive soft tissue disruption including vascular insufficiency to the leg secondary to popliteal artery injury. Physical exam may miss vascular injury and possible late occlusion, but there is controversy regarding use of ...
