Role of radiology techniques and hybrid PET-MRI technique in the diagnosis of pharmacoresistant epilepsy
The surgical treatment outcome in patients with pharmacoresistant epilepsy directly depends on the epileptic focus localization accuracy. Conventional diagnostic algorithms for patients with epilepsy involve starting with video EEG monitoring and magnetic resonance imaging. It is not possible to localize epileptogenic foci with the use of these techniques in a large segment of patients with pharmacoresistant epilepsy, or the test results are discordant. The review provides the analysis of literature data on the current possibilities of SPECT, PET and new hybrid PET-MRI technique when used for preoperative planning in patients with refractory epilepsy.
