Normal 18F-FDG PET">brain 18F-FDG PET images, consecutively recorded on analog and fully digital PET cameras in an 85-year-old woman, are depicted herein with the reconstruction methods recommended for a 2-mm voxel size on each camera and with a high-resolution reconstruction additionally developed for digital PET with a 1-mm voxel size. An enhanced gray-to-white matter contrast was consistently documented for digital PET when compared with analog PET, and was associated with a further enhancement in spatial resolution at 1-mm voxel size, as evidenced by a much clearer delineation of cortical gyri. These high-resolution images could favor the identification of brain abnormalities.
