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\u2010field systems. Here, we deployed a portable ultra\u2010low\u2010field 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\u2010ictal MRI abnormalities in the seizure onset zone. A .064\u2010T Swoop Portable MR Imaging System was used. Postictally, an axial diffusion\u2010weighted sequence was acquired. The interictal MRI consisted of the diffusion\u2010weighted and three\u2010dimensional T1\u2010weighted sequences. Postictal\u2013interictal difference maps of diffusion\u2010weighted volumes were calculated. Three individuals were included. Two individuals with focal aware seizures scanned 29\u2009s and 19\u2009min after the seizure, respectively, showed focal restrictions in diffusivity in the seizure onset zone, and a third individual scanned 5\u2009h 45\u2009min after a focal to bilateral tonic\u2013clonic seizure showed global restrictions of diffusivity. Portable ultra\u2010low\u2010field 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.<\/jats:p>","DOI":"10.1111\/epi.18273","type":"journal-article","created":{"date-parts":[[2025,2,18]],"date-time":"2025-02-18T07:37:20Z","timestamp":1739864240000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Portable
