Application progress of 7T ultra⁃high field MRI in diagnosis and treatment of drug⁃resistant epilepsy

Abstract

7T ultra⁃high field MRI (7T MRI), with its high resolution, high signal⁃to⁃noise ratio (SNR) and high contrast, is superior to conventional field intensity MRI in clinical applications such as diagnosis of hippocampal sclerosis (HS) and focal cortical dysplasia (FCD), assisting in the identification of pathological subtypes of the both, locating the scope of surgical excision, and has made progress in the diagnosis and treatment of drug⁃resistant epilepsy (DRE). This paper aims to review the clinical application value and research progress of 7T MRI in order to promote its application in the field of diagnosis and treatment of epilepsy.
