High-resolution vessel wall magnetic resonance imaging of carotid and intracranial vessels.

High-resolution vessel wall magnetic resonance imaging of carotid and intracranial vessels. Acta Radiol. 2019 Feb 06;:284185119826538 Authors: Sui B, Gao P Abstract Carotid and intracranial imaging play an essential role in the comprehensive evaluation and prevention for stroke patients. High-resolution vessel wall magnetic resonance imaging (HR VW-MRI) has been applied in carotid and intracranial arteries with optimal ability in displaying the features of various vascular diseases. Recent advanced MRI techniques can not only help in the differential diagnosis of vascular diseases but can also provide information on pathogenesis exploration of underlying mechanisms, follow-up monitoring, and determination of prognosis for patients with cerebral strokes. The aim of this article was to review the applications of HR VW-MRI in various pathologic conditions of carotid and intracranial arterial imaging. PMID: 30727746 [PubMed - as supplied by publisher]

GravesAbstractAutomatic identification of brain lesions from magnetic resonance imaging (MRI) scans of stroke survivors would be a useful aid in patient diagnosis and treatment planning. It would also greatly facilitate the study of brain-behavior relationships by eliminating the laborious step of having a human expert manually segment the lesion on each brain scan. We propose a multi-modal multi-path convolutional neural network sys...

This study demonstrates that body part-specific somatosensory imagery differentially activates somatosensory cortex in a topographically specific manner; evidence which was surprisingly still lacking in the literature. It also offers proof of concept for a novel somatosensory imagery-based fMRI-BCI control strategy, with particularly high potential for visually and motor-impaired patients. The strategy could also be transferred to lower MRI field strengths and to mobile functional near-infrared spectroscopy. Finally, given that communication BCIs provide the BCI user with a form of feedback based on their brain signals and...

This study evaluated the morphological changes of the lower limb and associated hemodynamic responses to different lower-body compression pressures (COMPs) in physically active, healthy individuals at rest. Each of the 32 participants underwent three trials with three different degrees of lower-body compression applied: “Low” (2.2±1.4 mmHg), “Medium” (12.9±3.9 mmHg), and “High” (28.8±8.3 mmHg). In each COMP, a cross-sectional area of leg muscles (CSAmuscle), subcutaneous fat (CSAfat), superficial vessels (SupV), deep arteries (DA), and deep veins...

Introduction: Carotid endarterectomy is an established surgical intervention that is associatedwith a reduction in the future risk of stroke in symptomatic patients. However, the identification of culprit carotid plaque remains challenging for number of reasons including the suboptimal evaluation of carotid plaque morphology, disease activity and future stroke risk stratification.

Introduction: Endarterectomy remains the gold standard in carotid artery revascularization because carotid artery stenting entails more embolization. But the Roadster trial with the transcervical approach showed excellent results, similar to CEA stroke rates. The new generation stent is supposed to reduce plaque prolapse and postoperative embolization. The use of this stent in combination with the transcervical approach could improve the Roadster results.

This study aims to investigate the indications, findings and outcomes of neuroimaging studies performed for burn injured patients.MethodsA retrospective case series study of adult burn patients admitted over an 8 year period was completed in the National Burns Centre at St James’s Hospital, Dublin. Neuroimaging studies carried out for patients admitted during the study period were reviewed by a Consultant Radiologist and Consultant Stroke Physician. Outcomes included neuroimaging findings, prevalence of white matter disease (Fazekas scale), length of stay, discharge destination, predicted and observed mortalit...

ConclusionsAcupuncture at one side could stimulate bilateral regions. CAT could evoke the gyrus which was possibly related to motor recovery from stroke. A promising indicator of neurobiological deficiencies could be represented by ReHo values in post-stroke patients.

In this case, we demonstrate the ability of diffusion weighted magnetic resonance imaging to localize retinal ischemia in a patient with acute vision loss. MRI is widely used for the evaluation of acute stroke, but there has only been one other case report showing the ability of DWI to rapidly localize retinal pathology, including central retinal artery occlusion [1]. Central retinal artery occlusion is an ocular emergency presenting with acute, painless loss of vision as a result of retinal ischemia.

CONCLUSIONS: According to the results of postoperative DW-MRI, retrograde perfusion itself might not increase the incidence of postoperative cerebral embolism in properly selected cardiac surgery patients undergoing routine preoperative CTA examination.
