Introduction:  Image  distortion  is  one  of  the  major  problems  of  magnetic  resonance  imaging  (MRI) for use in 3DMRI, velocity MRI, FMRI and radiotherapy treatment planning (RTTP). It is  widely known that the most obvious effect of the inhomogenity of the magnetic fields and the  nonlinearity  of  the  gradient  is  the  Geometric  Distortion  of  MR  tomograms.  In  this  study,  the...

• Applications of fMRI, EEG, fNIRS and MEG in road safety driving behaviour research analysed. (Dis)advantages each neuroimaging method various experiments discussed. EEG found to be the most popular experiments, followed by fMRI. fMRI studies mostly experimented neural effects recreational drugs distractive stimuli. predominantly focused on driver fatigue detection sleepiness. methods have sub...

Abstract Background While advances in the field of functional magnetic resonance imaging (fMRI) provide new opportunities to study brain networks underlying experience hallucinations psychosis, there are methodological challenges unique symptom-capture studies. Study Design We extracted activated during hallucination-capture for schizophrenia patients when fMRI data collected from two sites was...

To explore the functional changes in whole brain network patients with sudden sensorineural hearing loss (SHL) at acute stage from magnetic resonance imaging (fMRI) evaluation results, 80 right SHL were selected as subjects (patient group). In addition, 40 healthy volunteers who underwent physical examination hospital during same period recruited a control group. fMRI was performed to analyze p...

In recent years there has been growing interest in measuring time-varying functional connectivity between different brain regions using resting-state magnetic resonance imaging (rs-fMRI) data. One way to assess the relationship signals from is measure their phase synchronization (PS) across time. There are several ways perform such analyses, and we compare methods that utilize a PS metric toget...

It is often difficult to predict seizure recurrence in subjects who have suffered a first-ever epileptic seizure. In this study, the predictive value of physiological signals measured using Electroencephalography (EEG) and functional MRI (fMRI) assessed. particular those patients developing epilepsy (i.e. second unprovoked seizure) that were initially evaluated as having low risk are interest.I...

Functional magnetic resonance imaging (fMRI) enables identification of the brain regions and networks underpinning cognitive tasks. It has potential to significantly advance design science, but is challenging apply in studies methodological guidance for researchers lacking. In this Research Note, we reflect on our experiences other work outline activities involved developing executing fMRI stud...

Functional magnetic resonance imaging (fMRI) is widely used to detect changes in the resting-state brain networks of migraine patients. connectivity fMRI analysis examines functional organization based on temporal correlations blood oxygen level-dependent signal different regions. Most previous studies have assumed that between regions remains relatively stable over time. However, it now known ...
