Abstract

Pulsed arterial spin-labeling (PASL) MRI (magnetic resonance imaging) is a recently developed, non-invasive technique for measuring the cerebral blood flow (CBF) in patients with cerebrovascular disease. In the case of partial epilepsy, there have been some reports indicating the value of PASL MRI in the interictal, and ictal states. However, none of the reports on the ictal state were conducted in surgical cases. Moreover, they did not refer to interictal or ictal CBF studies, which are commonly used for the localization of the epileptogenic zone. We herein report a surgical case of cortical dysplasia with status epilepticus in which PASL MRI was useful for localizing the epileptic focus, compared with interictal and peri-ictal ECD-SPECT.
