Cross-sectional imaging studies are known to play a significant role in the evaluation of epilepsy patients. However no single technique of neuroimaging is free of drawbacks to diagnose epilepsy and ascertain the pathophysiological basis. Comparative studies on these techniques have remained largely inconclusive with no clear differentiation between these in terms of pathophysiological basis and diagnostic or prognostic specificity with conflicting reports on their individual superiority. So it is important to find out the relative sensitivity of different techniques with regard to non-invasive detection and localization of epileptogenic lesions having organic basis such as vascular abnormalities, tumours, and infarcts that would be amenable to surgical treatment. Here, we compared the different imaging modalities and their specific role in patients with epilepsy. In this study it was concluded that PET is superior in detecting epileptic lesions as compared to then EEG ,CT,MRI, and MRS. At the same time MRS is superior to PET in its ability to detect bilateral abnormalities. |
