AJNR Am J Neuroradiol
. 2023 Jul;
44(8):974-982.
PMID: 37474265
Background And Purpose: Prior studies have found an association between calcification and the epileptogenicity of tubers in tuberous sclerosis complex. Quantitative susceptibility mapping is a novel tool sensitive to magnetic...

. 2021 Feb;
42(4):774-781.
PMID: 33602745
Background And Purpose: Head motion causes image degradation in brain MR imaging examinations, negatively impacting image quality, especially in pediatric populations. Here, we used a retrospective motion correction technique in...

Neuroimage
. 2016 Aug;
146:438-451.
PMID: 27554531
Although it has been consistently found that local blood-oxygen-level-dependent (BOLD) changes are better modelled by a combination of the power of multiple EEG frequency bands rather than by the power...

Neuroimage
. 2016 Aug;
142:371-380.
PMID: 27498370
In current fMRI studies designed to map BOLD changes related to interictal epileptiform discharges (IED), which are recorded on simultaneous EEG, the information contained in the morphology and field extent...

Pedreira C, Vaudano A, Thornton R, Chaudhary U, Vulliemoz S, Laufs H, et al.
Neuroimage
. 2014 May;
99:461-76.
PMID: 24830841
Scalp EEG recordings and the classification of interictal epileptiform discharges (IED) in patients with epilepsy provide valuable information about the epileptogenic network, particularly by defining the boundaries of the "irritative...

. 2012 Jun;
63(1):301-9.
PMID: 22652020
We have recently performed simultaneous intracranial EEG and fMRI recordings (icEEG-fMRI) in patients with epilepsy. In this technical note, we examine limited thermometric data for potential electrode heating during our...

Neuroimage
. 2012 Mar;
61(4):1383-93.
PMID: 22450296
Rationale: To improve the sensitivity and specificity of simultaneous electroencephalography and functional magnetic resonance imaging (EEG-fMRI) it is prudent to devise modelling strategies explaining the residual variance. The purpose of...

. 2009 Dec;
49(4):3219-29.
PMID: 19948231
Introduction: EEG-correlated fMRI (EEG-fMRI) studies can reveal haemodynamic changes associated with Interictal Epileptic Discharges (IED). Methodological improvements are needed to increase sensitivity and specificity for localising the epileptogenic zone. We...

. 2009 May;
46(3):834-43.
PMID: 19408351
Simultaneous EEG-fMRI acquisitions in patients with epilepsy often reveal distributed patterns of Blood Oxygen Level Dependant (BOLD) change correlated with epileptiform discharges. We investigated if electrical source imaging (ESI) performed...
