Purpose: To assess the trends in administered 2-[F]fluoro-2-deoxy-D-glucose ([F]FDG) doses, computed tomography (CT) radiation doses, and image quality over the last 15 years in children with drug-resistant epilepsy (DRE) undergoing hybrid positron emission tomography (PET) brain scans.
Methods: We retrospectively analyzed data from children with DRE who had [F]FDG-PET/CT or magnetic resonance scans for presurgical evaluation between 2005 and 2021. We evaluated changes in injected [F]FDG doses, administered activity per body weight, CT dose index volume (CTDIvol), and dose length product (DLP).
Article Synopsis
- * The study involved 140 healthy older adults and 49 with mild cognitive impairment, using techniques like APOE genotyping and MRI to measure GSH levels in the brain.
- * Findings indicated that higher GSH levels are more common in females, while older age and the presence of the APOE4 genotype are associated with increased amyloid levels, highlighting sex-specific differences in GSH levels among older adults.
Introduction: We investigated the interactive associations between amyloid and hypertension on the entorhinal cortex (EC) tau and atrophy and the role of cerebral blood flow (CBF) as a shared mechanism by which amyloid and hypertension contribute to EC tau and regional white matter hyperintensities (WMHs).
Methods: We analyzed data from older adults without dementia participating in the Add-Tau study (NCT02958670, n = 138) or Alzheimer's Disease Neuroimaging Initiative (ADNI) (n = 523) who had available amyloid-positron emission tomography (PET), tau-PET, fluid-attenuated inversion recovery (FLAIR), and T1-weighted magnetic resonance imaging (MRI). A subsample in both cohorts had available arterial spin labeling (ASL) MRI (Add-Tau: n = 78; ADNI: n = 89).
According to the new WHO classification of 2021, gliomas are a heterogeneous group of tumors with very different histology, molecular genetics, and prognoses. In addition to glioblastomas, the most common gliomas, there are also numerous less common gliomas, some of which have a very favorable prognosis. Targeted radionuclide therapy is a therapeutic option that can be attractive if a tumor can be targeted based on its molecular characteristics.

Current evidence is exclusively based on populations from the U.S.
