Perfusion imaging predicts short‐term clinical outcome in isolated posterior cerebral artery occlusion stroke

by Clinical Neuropsychologist | Tuesday, September 3, 2024 | Neuroimaging

Abstract Background and Purpose Ischemic strokes due to isolated posterior cerebral artery (PCA) occlusions represent 5% of all strokes but have significant impacts on patients’ quality of life, primarily due to visual deficits and thalamic involvement. Current...

Reliability of quantitative magnetic susceptibility imaging metrics for cerebral cortex and major subcortical structures

by Clinical Neuropsychologist | Friday, August 30, 2024 | Neuroimaging

Abstract Background and purpose Susceptibility estimates derived from quantitative susceptibility mapping (QSM) images for the cerebral cortex and major subcortical structures are variably reported in brain magnetic resonance imaging (MRI) studies, as average of all...

Serum glial fibrillary acidic protein as a marker of brain MRI metrics in multiple sclerosis: A scoping review

by Clinical Neuropsychologist | Friday, August 23, 2024 | Neuroimaging

Abstract Background and Purpose Magnetic resonance imaging (MRI) is heavily relied upon for the diagnosis and monitoring of multiple sclerosis (MS), a chronic, demyelinating disease of the central nervous system. Serum biomarkers may serve as an accessible tool for...

Dynamic degree centrality in stroke‐induced Broca’s aphasia varies based on first language: A functional MRI study

by Clinical Neuropsychologist | Friday, August 23, 2024 | Neuroimaging

Abstract Background and Purpose This study sought to explore dynamic degree centrality (DC) variability in particular regions of the brain in patients with poststroke Broca aphasia (BA) using a resting-state functional magnetic resonance imaging (rs-fMRI) approach,...

Contrast‐free visualization of distal trigeminal nerve segments using MR neurography

by Clinical Neuropsychologist | Friday, August 23, 2024 | Neuroimaging

Abstract Background and Purpose The 3-dimensional cranial nerve imaging (CRANI) sequence may assist visualization of anatomical details of extraforaminal cranial nerves and aid in clinical diagnosis and preoperative planning. In this study, we investigated the...
