Abstract
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.
期刊介绍：
The first issue of the Revue Neurologique, featuring an original article by Jean-Martin Charcot, was published on February 28th, 1893. Six years later, the French Society of Neurology (SFN) adopted this journal as its official publication in the year of its foundation, 1899.
The Revue Neurologique was published throughout the 20th century without interruption and is indexed in all international databases (including Current Contents, Pubmed, Scopus). Ten annual issues provide original peer-reviewed clinical and research articles, and review articles giving up-to-date insights in all areas of neurology. The Revue Neurologique also publishes guidelines and recommendations.
The Revue Neurologique publishes original articles, brief reports, general reviews, editorials, and letters to the editor as well as correspondence concerning articles previously published in the journal in the correspondence column.
