Tīmeklisacquired and the following week an [18F]-FMZ PET scan (3.6–4.6 nmol). The PET data was co-registered to the MRI and regions of interest drawn on the MRI for selected structures. A PSM was used to derive receptor density and apparent affinity from the [18F]-FMZ PET data. Key Findings:The PSM was found to adequately model [18F] … Tīmeklis2024. gada 26. jūn. · Abstract.
