abstract = {The detection of transient peri-ictal magnetic resonance
imaging (MRI) abnormalities has been variable after
epileptic seizures. The most common reason for this
variability is that abnormalities may disappear if the
interval between seizure and scan acquisition is prolonged
using conventional high-field systems. Here, we deployed a
portable ultra-low-field MRI system in the presurgical
evaluation at the bedside of individuals with epilepsy. We
hypothesized that this novel technology enables rapid
postictal scans and reliably shows focal peri-ictal MRI
abnormalities in the seizure onset zone. A .064-T Swoop
Portable MR Imaging System was used. Postictally, an axial
diffusion-weighted sequence was acquired. The interictal MRI
consisted of the diffusion-weighted and three-dimensional
T1-weighted sequences. Postictal-interictal difference maps
of diffusion-weighted volumes were calculated. Three
individuals were included. Two individuals with focal aware
seizures scanned 29 s and 19 min after the seizure,
respectively, showed focal restrictions in diffusivity in
the seizure onset zone, and a third individual scanned 5 h
45 min after a focal to bilateral tonic-clonic seizure
showed global restrictions of diffusivity. Portable
ultra-low-field MRI opens a new line of inquiry with the aim
to establish postictal seizure imaging as part of the
presurgical evaluation of people with epilepsy.},
