THE CANADIAN JOURNAL OF NEUROLOGICAL SCIENCES PET Scanning in Partial Epilepsy
Many biologically active tracers are available for positron emission tomography (PET) investigations, but most studies of epilepsy have utilized F-fluorodeoxyglucose (FDG) to measure local cerebral metabolic rate for glucose. Over 70% of patients with medically refractory partial seizures demonstrate an interictal zone of hypometabolism corresponding to the epileptogenic region. This metabolic ...
متن کاملPET studies in epilepsy.
Various PET studies, such as measurements of glucose, serotonin and oxygen metabolism, cerebral blood flow and receptor bindings are availabe for epilepsy. (18)Fluoro-2-deoxyglucose ((18)F-FDG) PET imaging of brain glucose metabolism is a well established and widely available technique. Studies have demonstrated that the sensitivity of interictal FDG-PET is higher than interictal SPECT and simi...
متن کامل[PET and SPECT in epilepsy].
Epilepsy is one of the most frequent chronic neurological disorders, affecting 1-2% of the population. Patients with complex partial drug resistant episodes may benefit from a surgical treatment consisting in the excision of the epileptogenic area. Localization of the epileptogenic area was classically performed with video-EEG and magnetic resonance (MR). Recently, functional neuroimaging studi...
متن کاملSeizure-related short-term plasticity of benzodiazepine receptors in partial epilepsy: a [11C]flumazenil-PET study.
We have undertaken a test-re-test [11C]flumazenil (FMZ) PET study in 10 drug-resistant epileptic patients, including six with a mesiotemporal epilepsy (MTE), and 10 normal controls, in order to investigate seizure-related short-term plasticity of benzodiazepine (BZD) receptors. All subjects underwent two FMZ-PET scans at a 1 week interval. Patients benefited from a concurrent video-EEG monitori...
