Meningeal contribution to migraine pain: a magnetic resonance angiography study

Brain : a journal of neurology, 2018
The origin of migraine pain is unknown but possibly implicates the dura mater, which is pain sensitive in proximity to the meningeal arteries.

Vascular magnetic resonance angiography techniques.

Cardiovascular Diagnosis and Therapy, 2019
Magnetic resonance angiography (MRA) denotes a unique option for the evaluation of peripheral vasculature due to its noninvasive nature, lack of ionizing radiation exposure, potential for non-contrast examination, and ability for generating volumetric ...

Fluorine-19 magnetic resonance angiography of the mouse. [PDF]

PLoS ONE, 2012
PURPOSE: To implement and characterize a fluorine-19 ((19)F) magnetic resonance imaging (MRI) technique and to test the hypothesis that the (19)F MRI signal in steady state after intravenous injection of a perfluoro-15-crown-5 ether (PCE) emulsion may be

Meta-analysis of computed tomography angiography versus magnetic resonance angiography for intracranial aneurysm

Medicine, 2018
Background: Whether the diagnosis value of computed tomography angiography (CTA) for intracranial aneurysm is in accordance with magnetic resonance angiography (MRA) remains inconclusive.

Quiescent-Interval Single-Shot Magnetic Resonance Angiography

Diagnostics, 2018
Lower extremity peripheral arterial disease (PAD) is a chronic, debilitating disease with a significant global burden. A number of diagnostic imaging techniques exist, including computed tomography angiography (CTA) and contrast-enhanced magnetic ...

The diagnostic value of non-contrast enhanced quiescent interval single shot (QISS) magnetic resonance angiography at 3T for lower extremity peripheral arterial disease, in comparison to CT angiography

Journal of Cardiovascular Magnetic Resonance, 2016
BackgroundThe high incidence of renal insufficiency in patients with Peripheral Arterial Disease raises the concern for nephrogenic systemic fibrosis (NSF) with respect to contrast enhanced MRA.

Use of Nuclear Magnetic Resonance Imaging Angiography to Follow-Up Arterial Remodeling in an Animal Model [PDF]

, 1998
Appropriately sized arteries in small animals may be possible models for studying the remodeling process as occurs after arterial balloon injury in humans. Magnetic resonance imaging (MRI) is able to noninvasively image tissue in vivo.

Pediatric jugular vein aneurysm (phlebectasia): report of two cases and review of the literature

Radiology Case Reports, 2017
Jugular vein aneurysms are rare vascular abnormalities that are most commonly encountered in the pediatric population. We report two separate cases in infants, both of whom presented with enlarging neck masses and were found to have jugular vein ...

Impact of incomplete ventricular coverage on diagnostic performance of myocardial perfusion imaging. [PDF]

, 2017
In the context of myocardial perfusion imaging (MPI) with cardiac magnetic resonance (CMR), there is ongoing debate on the merits of using technically complex acquisition methods to achieve whole-heart spatial coverage, rather than conventional 3-slice ...

Ghost magnetic resonance angiography [PDF]

Magnetic Resonance in Medicine, 2009
AbstractTraditional methods for magnetic resonance angiography (MRA) involve the radiofrequency excitation of vascular spins within a selected region of tissue, followed by gradient localization and imaging of those spins within that same region.
