Utility of MRI, PET, and ictal SPECT in presurgical evaluation of non-lesional pediatric epilepsy


Diagnostic brain imaging has been widely utilized and plays a pivotal role in the presurgical evaluation of children with epilepsy. Despite a daunting amount of data accumulated in the past three decades, evidence-based guidelines for the use of various imaging modalities in the clinical management of pediatric epilepsy are missing. A report of ILAE Task Forces and Commissions in 2014 on diagnostic tests in the evaluation for resective surgery in epileptic children cited several shortcomings of the available data, including the lack of class 1 and 2 evidence establishing the relative utility of each test in specific clinicopathologic cohorts [1].
