Transcutaneous auricular vagus nerve stimulation in drug‐resistant epilepsy: A randomized, sham‐controlled crossover trial with exploratory EEG and MRI response phenotyping

Epilepsia Open, EarlyView.
Abstract Objective Transcutaneous auricular vagus nerve stimulation (taVNS) is a noninvasive neuromodulation strategy for drug‐resistant epilepsy, but clinical response is heterogeneous. We examined whether electroencephalographic (EEG) and structural magnetic resonance imaging (MRI) phenotypes were associated with active‐specific clinical benefit from

Reduction in Cerebral Blood Flow in Areas Appearing as White Matter Hyperintensities on Magnetic Resonance Imaging [PDF]

, 2009
The purpose of this study was to examine cerebral blood flow (CBF) as measured by arterial spin labeling (ASL) in tissue classified as white matter hyperintensities (WMH), normal appearing white matter, and grey matter.

Research progress on the use of the optical coherence tomography system for the diagnosis and treatment of central nervous system tumors

Ibrain, Volume 11, Issue 1, Page 3-18, Spring 2025.
With the advantages of high‐resolution imaging, efficient image acquisition, intraoperative real‐time detection, and radiation‐free and noninvasive characteristics, optical coherence tomography (OCT) provides accurate diagnosis and effective intraoperative guidance for the minimally invasive diagnosis and treatment of central nervous system (CNS ...

White Matter Hyperintensities Improve Ischemic Stroke Recurrence Prediction

, 2017
BACKGROUND: Nearly one in 5 patients with ischemic stroke will invariably experience a second stroke within 5 years. Stroke risk stratification schemes based solely on clinical variables perform only modestly in non-atrial fibrillation (AF) patients and ...

Manual segmentations of white matter hyperintensities from a subset of 7 ADNI subjects scanned three consecutive years, for inter-/intra-observer reliability analyses [PDF]

, 2017
This dataset contains structural magnetic resonance imaging (MRI)-derived data from 7 randomly selected participants enrolled in the Alzheimer’s Disease Neuroimaging Initiative (ADNI) project. These data are binary masks of white matter hyperintensities (

Functional Imaging for Identification of Functionally Critical Brain Regions to Spare in Glioma Radiation Therapy Planning: A Systematic Review

Journal of Medical Radiation Sciences, EarlyView.
This review highlights the role of functional imaging in sparing cognitive brain regions during glioma radiotherapy. It shows promising dose reduction without compromising target coverage, but evidence remains limited, requiring standardisation and prospective validation.

Structural Carotid Atherosclerosis and Mild Behavioral Impairment: A Cross‐Sectional Study in a Community‐Dwelling Population

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Mild behavioral impairment (MBI) is a late‐life neuropsychiatric syndrome proposed as an early clinical manifestation of neurodegenerative disease. Vascular pathology contributes to late‐life cognitive and behavioral changes; however, its relationship with MBI remains insufficiently characterized.

Persistent symmetrical white matter hyperintensities: a case report

Journal of Medical Case Reports
Introduction White matter hyperintensities on magnetic resonance imaging are a frequent finding. Anaplastic astrocytoma as a cause of persistent, symmetrical white matter hyperintensities is unusual.
