Topology‐aware anatomical segmentation of the Circle of Willis: HUNet unveils the vascular network

open access: yesIET Image Processing
This research investigates the Circle of Willis, a critical vascular structure vital for cerebral blood supply. A modified novel dual‐pathway multi‐scale hierarchical upsampling network (HUNet) is presented, tailored explicitly for accurate segmentation ...

Hyperacute Interleukin‐1β Production and Neutrophil Extracellular Trap Formation in the Cerebral Circulation of Stroke Patients with Large Vessel Occlusion

open access: yesAnnals of Neurology, EarlyView.
Acute ischemic stroke due to large vessel occlusion is associated with rapid intravascular immune activation. Analysis of arterial blood sampled distal to the thrombus during mechanical thrombectomy revealed increased extracellular adenosine triphosphate (ATP) and interleukin‐1β (IL‐1β) levels, evidence of inflammasome priming in monocytes, and ...

Rapid development of a mycotic aneurysm of the intracranial artery secondary to Scedosporium apiospermum sinusitis

open access: yesMedical Mycology Case Reports, 2016
An 85-year-old man complained of a 2-month history of pain on the left side of his face. Brain computed tomography (CT) and magnetic resonance imaging/magnetic resonance angiography did not clearly show any intracranial abnormality and only showed fluid ...

Application of 3D‐Slicer combined with 3D printing technology in training neurosurgery resident physicians' imaging spatial cognition and clinical reasoning: A self‐controlled before‐ and after‐study

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Neurosurgical residency training requires advanced spatial cognition and 3D anatomical understanding, which traditional methods often fail to adequately develop. This study evaluated a novel educational model integrating 3D Slicer and 3D printing technology to enhance imaging spatial cognition and clinical reasoning among neurosurgery ...

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

Small‐Vessel Disease and Intracranial Large Artery Disease in Brain MRI Predict Dementia and Acute Coronary Syndrome, Respectively: A Prospective, Observational Study in the Population at High Vascular Risk

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background We aimed to clarify the predictive value of cerebral small‐vessel disease and intracranial large artery disease (LAD) observed in magnetic resonance imaging of the brain and magnetic resonance angiography on future vascular events and ...

Optimized Hemodynamic Assessment to Predict Stroke Risk in Vertebrobasilar Disease: Analysis From the VERiTAS Study

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Atherosclerotic vertebrobasilar disease is a significant etiology of posterior circulation stroke. The prospective observational VERiTAS (Vertebrobasilar Flow Evaluation and Risk of Transient Ischemic Attack and Stroke) study demonstrated that

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Atherosclerotic changes in an intrasellar persistent trigeminal artery in a patient presenting with dizziness: a case report from Korea [PDF]

open access: yesThe Ewha Medical Journal
We present a rare case of a 68-year-old woman who experienced dizziness, nausea, vomiting, and imbalance for 2 months. Imaging studies, including magnetic resonance imaging, magnetic resonance angiography, and digital subtraction angiography, revealed an
