Abstract:
Ictal single photon emission computed tomography (SPECT) reflects epileptic activity through hyperperfusion associated with ictal discharge. It provides valuable spatial information on ictal activity, but its temporal resolution is limited. Therefore, information provided by SPECT is not restricted to the epileptogenic zone, but demonstrates a larger epileptogenic network, related to the spatiotemporal dynamics of ictal processes. This review includes a description of the technique, followed by a description of the different parameters likely to influence the ictal perfusion images. SPECT gives contributes original diagnostic data to the decision-making process which will complete, the other evaluation parameters.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
