H2(15)O or 13NH3 PET and electromagnetic tomography (LORETA) during partial status epilepticus

Neurology. 2005 Nov 22;65(10):1657-60. doi: 10.1212/01.wnl.0000184516.32369.1a.

Abstract

The authors evaluated the feasibility and source localization utility of H2(15)O or 13NH3 PET and low-resolution electromagnetic tomography (LORETA) in three patients with partial status epilepticus (SE). Results were correlated with findings from intraoperative electrocorticographic recordings and surgical outcomes. PET studies of cerebral blood flow and noninvasive source modeling with LORETA using statistical nonparametric mapping provided useful information for localizing the ictal activity in patients with partial SE.
