25 de ene. de 2024 · MR vessel wall imaging (VW-MRI) refers to MRI techniques used to evaluate for disease within the walls of arteries, beyond the luminal abnormalities depicted on angiographic imaging. This can be used anywhere in the body but is particularly important intracranially in distinguishing between various causes of luminal stenosis such as ...
27 de jul. de 2021 · Accurate interpretation of intracranial vessel wall (VW) MRI findings in clinical practice requires understanding the conditions of adequate flow suppression, optimal spatial resolution, and reasons for enhancement after administration of a gadolinium-containing contrast agent.
20 de dic. de 2017 · Intracranial vessel wall magnetic resonance (MR) imaging has gained much attention in the past decade and has become part of state-of-the-art MR imaging protocols to assist in diagnosing the cause of ischemic stroke. With intracranial vessel wall imaging, vessel wall characteristics have tentatively been described for atherosclerosis ...
MR imaging characterization of the vessel wall requires suppression of MR imaging signal arising from luminal blood and CSF (or brain parenchyma for a vessel residing adjacent to the brain) (Fig 1 C, -D). Blood-suppression techniques usually exploit the condition of blood flowing and the vessel wall being stationary.
Vessel wall MR imaging (VW-MRI) has been introduced into clinical practice and applied to a variety of diseases, and its usefulness has been reported. High-resolution VW-MRI is essential in the diagnostic workup and provides more information than other routine MR imaging protocols.
PMID: 27469212. PMCID: PMC7963837. DOI: 10.3174/ajnr.A4893. Abstract. Intracranial vessel wall MR imaging is an adjunct to conventional angiographic imaging with CTA, MRA, or DSA. The technique has multiple potential uses in the context of ischemic stroke and intracranial hemorrhage.
Intracranial vessel wall MR imaging (VWI) is a diagnostic imaging technique used to assess and differentiate intracranial vasculopathies. 1 Conventional vessel imaging techniques, such as computed tomography angiography, digital subtraction angiography, and magnetic resonance angiography, show changes in lumen caliber, which are common morpholog...
