This report presents the case of a 61-year-old woman with assessment of fronto-temporo-sphenoidal refractory meningioma before radionuclide therapy with pretherapeutic 68Ga-DOTATOC PET/CT. Given the discovery of osteolytic lesions, 18F-FDG PET/CT is planned to search for the primitive origin. Meningioma bone metastasis is confirmed with spine biopsies.

This study aims to determine the effect of applying Point Spread Function (PSF) deconvolution, which is known to improve contrast and spatial resolution in brain F-FDG PET images, to the diagnostic thinking efficacy in Alzheimer's disease (AD). We compared Hoffman 3-D brain phantom images reconstructed with or without PSF. The effect of PSF deconvolution on AD diagnostic clinical performance was determined from digital brain F-FDG PET images of AD ( = 38) and healthy ( = 35) subjects compared to controls ( = 36).
