Multicenter, intraindividual comparison of single-dose gadobenate dimeglumine and double-dose gadopentetate dimeglumine for MR angiography
of the supra-aortic arteries (the Supra-Aortic VALUE study).
Short versus long echo time for cranial MR angiography
in children and adults.
Carotid MR angiography
of the patient showed no stenosis of the carotid artery on the symptomatic side.
Signal-to-noise (SNR) and contrast-to-noise (CNR) measurements were performed in data sets of the time-resolved MR angiography
(TWIST) and high-resolution 3D FLASH imaging.

of spinal vascular malformations," American Journal of Neuroradiology, vol.
Likewise, Figure 2 showing large hepatic cyst in right lobe of liver turned out to be portal vein aneurysm done by MR angiography
This guide introduces the basics of magnetic resonance imaging, covering its physics from basic principles to more advanced topics, such as MR angiography
and fast scanning techniques, and techniques made possible with high-performance gradients, such as echo planar imaging.
revealed marked narrowing of supraclinoid and intracavernous portion of left internal carotid artery and nonvisualization of right middle cerebral artery and anterior cerebral (A-1 segment) arteries (fig-2).
CT angiography or MR angiography
is commonly performed to demonstrate aneurysmal and nonaneurysmal changes including larger aneurysms and stenosis of the medium-sized vessels.
showed incomplete occlusion of both VAs while the basilar artery is without thrombotic formations (Figure 1).
described the use of 3D time of flight MR angiography
and demonstrated an accuracy of 86%, sensitivity of 91%, and a specificity of 81% in detection of aortic arch and aortic arch branch vessel lesions, as well as accurately determining severity of the lesion in comparison with angiography.
Phase-contrast MR angiography
, a noninvasive MR based flow-related technique, was employed to acquire hemodynamic data in selected intra-abdominal vessels at baseline and after 4 weeks of NSBB therapy.
