Evaluation of Source Generators in Partial Seizures ― Availability of Neuroradiological Images Superimposed on the Dipole Tracing ―

To clarify the anatomical localization of epileptic foci in childhood partial seizures, the source generators of interictal focal spikes were analyzed using a dipole tracing method and the effectiveness of a composite image diagnostic technique using neuroradiological images obtained by magnetic resonance imaging and single photon emission computed tomography was evaluated. The localization of electric source generators approximately reflects the abnormal lesions on neuroradiological images. However, the source generators tended to be located in the deep and/or peripheral parts of the abnormal regions. Even though systemic shifts in the position of optimal dipoles from their true positions is a limitation that must be taken into consideration, composite image diagnostic technique may be useful for evaluating the epileptogenic regions in partial seizures, and particularly, in children where noninvasive methods are preferable.
