9.4‐Tesla magnetic resonance imaging in focal epilepsy patients with high‐resolution surface‐based profiling of focal cortical dysplasias

Epilepsia, EarlyView.
Abstract Objective The detection of subtle epileptogenic lesions such as focal cortical dysplasias (FCDs) is a clinical challenge in the management of drug‐resistant focal epilepsy (DRFE). Ultra‐high‐field (UHF) magnetic resonance imaging (MRI) offers increased signal‐to‐noise ratios and spatial resolution compared to 3‐T MRI and may improve diagnostic

Cortical morphology alterations in non-COVID-19 post-infectious olfactory dysfunction

Scientific Reports
While COVID-19-associated olfactory dysfunction leads to gray matter (GM) structural alterations, it remains unclear whether these structural GM alterations are specific to COVID-19.

Artificial intelligence in preclinical epilepsy research: Current state, potential, and challenges

Epilepsia Open, EarlyView.
Abstract Preclinical translational epilepsy research uses animal models to better understand the mechanisms underlying epilepsy and its comorbidities, as well as to analyze and develop potential treatments that may mitigate this neurological disorder and its associated conditions. Artificial intelligence (AI) has emerged as a transformative tool across

Neural Correlates of Congenital Amusia

Pediatric Neurology Briefs, 2006
Magnetic resonance T1-weighted images were analyzed, using voxel-based morphometry (VBM), to detect brain anatomical differences in two independent groups of adults with congenital amusia (or tone-deafness) compared to controls with normal pitch ...

Cerebral grey matter density is associated with neuroreceptor and neurotransporter availability: A combined PET and MRI study

NeuroImage, 2021
Positron emission tomography (PET) can be used for in vivo measurement of specific neuroreceptors and transporters using radioligands, while voxel-based morphometric analysis of magnetic resonance images allows automated estimation of local grey matter ...

Quantifying extra‐lesional interhemispheric cortical asymmetry in focal cortical dysplasia type II

Epilepsia Open, EarlyView.
Abstract Objective Focal cortical dysplasia type II (FCDII) is a cortical malformation representing a common cause of surgically treatable drug‐resistant epilepsy. We studied whether FCDII disrupts normal structural interhemispheric asymmetry beyond the lesion location and quantified these asymmetries derived from structural magnetic resonance imaging (
