Diagnostic accuracy of 4D-MRA for the detection and localization of spinal dural arteriovenous fistulas: A retrospective 10-year cohort study.

Research Question: The goal of this study was to assess the diagnostic accuracy of spinal time-resolved contrast-enhanced MR angiography (4D-MRA) for the detection and localization of spinal dural arteriovenous fistulas (SDAVF) in our institution.

Material And Methods: Single center retrospective cohort study of patients with the clinical suspicion of a SDAVF. Patients were included who had undergone spinal 4D-MRA in the period January 2010-February 2021.

A Case of a Large Brain Metastasis: Time for Multidisciplinary Consultation.

Patients with complex diseases are mostly treated in a multidisciplinary setting. The impact of multidisciplinary care cannot be emphasized enough as it has the potential to significantly increase survival and, in some cases, help avoid a risky treatment approach. The aim of this case illustration is to emphasize the importance of multidisciplinary treatment and learn from the different approaches that can be made while treating such patients.

White matter integrity and cognitive performance in the subacute phase after ischemic stroke in young adults.

Introduction: Reduced white matter integrity outside the stroke lesion may be a potential contributor of post-stroke cognitive impairment. We aimed to investigate how a stroke lesion affects the integrity of surrounding white matter, and whether the integrity of the non-lesioned part of white matter tracts is associated with cognitive performance after ischemic stroke in young adults.

Methods: Patients from the ODYSSEY study, aged 18-49 years, with a first-ever ischemic stroke, underwent 3T MRI and cognitive assessment within six months after the index event.

Ultrasound Strain Imaging for Characterizing Atherosclerotic Plaque in the Carotid Arteries of Asymptomatic Subjects.

Objective: The rupture of vulnerable plaques in the carotid artery is a leading cause of strokes. While magnetic resonance imaging (MRI) is the standard for quantifying plaque composition, its high costs and lengthy procedure times limit large-scale use. Compound ultrasound strain imaging (CUSI) ultrasound offers a non-invasively alternative by assessing tissue deformation/strain within the arterial wall.

In-vivo cerebral artery pulsation assessment with Dynamic computed tomography angiography.

Four-Dimensional Computed Tomography Angiography (4D CTA) seems a promising technique for capturing vessel motion of cerebral arteries, which may help to assess pathological conditions such as intracranial aneurysms. The goal of our current observational study is to capture the lumen diameter of cerebral arteries during three subsequent cardiac cycles with 4D CTA and to assess vessel motion, anticipating consistent expansion patterns within each cardiac cycle. Eighteen adult patients with unruptured and untreated intracranial aneurysms were recruited at Radboud University Medical Center.
