Status epilepticus (SE) represents one of the most common neurological
emergencies, associated with high mortality and an important risk of functional
sequelae in survivors. Magnetic resonance imaging (MRI) offers the possibility
of early and noninvasive observation of seizure-induced parenchymal disturbances
secondary to the epileptic process. In the present review, we propose a
descriptive and comprehensive understanding of current knowledge concerning
seizure-induced MRI abnormalities in SE, also called peri-ictal MRI
abnormalities (PMAs). We then discuss how PMAs, as a noninvasive biomarker,
could be helpful to optimize patient prognostication in SE management. Finally,
we discuss alternative promising MRI approaches, including arterial spin
labeling (ASL), susceptibility-weighted imaging (SWI), dynamic contrast-enhanced
(DCE) MRI and dynamic susceptibility contrast (DSC) MRI that could refine our
understanding of SE, particularly in non-convulsive form.
