Tīmeklis2012. gada 1. maijs · FMZ PET, FDG PET and MRI were performed for epileptic focus localization. Confirmation of epileptic focus was based on inpatient video-electroencephalography (EEG). PET was analyzed using a statistical parametric mapping (SPM) method. MRI was analyzed by 2 experienced investigators. Tīmeklis2001. gada 26. jūn. · [11C]flumazenil (FMZ) PET is significantly more sensitive than 2-deoxy-2-[18F]fluoro-d-glucose (FDG) PET for the detection of cortical regions of seizure onset and frequent spiking in patients with extratemporal lobe epilepsy, whereas both FDG and FMZ PET show low sensitivity in the Detection of cortical areas of rapid …

Tīmeklis2016. gada 27. jūl. · Flumazenil (FMZ) is a benzodiazepine receptor antagonist. Labeled with carbon 11 ( 11 C), it is an excellent PET marker for cerebral benzodiazepine receptor density. Since the receptors are located on the neurons, reduction in receptor density may indicate neuronal loss, as is typical in a sclerotic region.
