    Uncinate fasciculus fiber tracking in mesial temporal lobe epilepsy. Initial findings

    In temporal lobe epilepsy (TLE) due to hippocampal sclerosis (HS), ictal discharge spread to the frontal and insulo-perisylvian cortex is commonly observed. The implication of white matter pathways in this pro...

    Optimized diffusion gradient orientation schemes for corrupted clinical DTI data sets

    Object:A method is proposed for generating schemes of diffusion gradient orientations which allow the diffusion tensor to be reconstructed from partial data sets in clinical DT-MRI, shoul...

    Slice acquisition order and blood oxygenation level dependent frequency content: an event-related functional magnetic resonance imaging study

    Many event-related functional magnetic resonance imaging paradigms performed so far have been designed to study a limited part of the brain with high temporal resolution. However, event-related paradigms can b...

    Regularization of MR diffusion tensor maps for tracking brain white matter bundles

    We propose a new way for tracking brain white matter fiber bundles in diffusion tensor maps. Diffusion maps provide information about mobility of water protons in different directions. Assuming that diffusion ...

    Echo planar imaging with a contrast medium in studying brain perfusion

    Echo planar imaging is a new MRI technique capable of producing images in short periods of time. This type of examination has the time resolution required to study the first passage of contrast medium through ...
