Compact Monocular Video‐Ophthalmoscope to Measure Retinal Reflectance Changes to Flicker Light Stimuli

Journal of Biophotonics, EarlyView.
This study presents a compact monocular VO that captures high‐frame‐rate retinal videos of the ONH during flicker light stimulation. The device demonstrated its ability to detect flicker‐induced changes in retinal parameters related to blood flow in healthy subjects, providing insights into temporal and spatial retinal variations.

Cerebral vasospasm affects arterial critical closing pressure. [PDF]

, 2014
The effect of cerebral vasospasm (CVS) after aneurysmal subarachnoid hemorrhage (SAH) on critical closing pressure (CrCP) has not been fully delineated. Using cerebral impedance methodology, we sought to assess the behavior of CrCP during CVS.

The Diagnostic Value of Contrast‐Enhanced Vessel Wall MRI for Diagnosing Neuropsychiatric Systemic Lupus Erythematosus

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Imaging biomarkers for neuropsychiatric systemic lupus erythematosus (NPSLE) are highly needed, and intracranial contrast‐enhanced vessel wall imaging (CE‐VWI) can potentially detect cerebral vessel wall abnormalities in lupus. Purpose To evaluate the diagnostic value of CE‐VWI in differentiating NPSLE from non‐NPSLE.

Involvement of Microglia in the Pathophysiology of Intracranial Aneurysms and Vascular Malformations—A Short Overview

International Journal of Molecular Sciences, 2021
Aneurysms and vascular malformations of the brain represent an important source of intracranial hemorrhage and subsequent mortality and morbidity. We are only beginning to discern the involvement of microglia, the resident immune cell of the central ...

Stroke Risk in Head and Neck Cancer: A Meta‐analysis of Reconstructed Individual Patient Survival Data

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Although previous studies suggest an increased stroke risk in head and neck cancer (HNC) survivors, the risk with various treatment modalities, including radiotherapy, is less certain. This study investigates stroke incidence and risk in HNC patients, including how different treatments influence stroke risk. Data Sources A literature

The FRED‐X Flow Diverter—An Australian Experience

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Background The FRED X flow diverter features antithrombotic surface treatment to reduce thrombogenicity. This study evaluated the safety and efficacy of FRED X in treating intracranial aneurysms in the Australian setting. Methods Clinical, procedural and imaging data were retrospectively reviewed for a consecutive series of patients at a ...

A Case of Severe Delayed Vasospasm after Clipping Surgery for an Unruptured Intracranial Aneurysm [PDF]

Neurointervention
Delayed ischemic stroke associated with intractable vasospasm after clipping of unruptured intracranial aneurysms (UIAs) has been rarely reported. We report a patient with delayed ischemic stroke associated with intractable vasospasm following UIA ...
