Comments Off on Recalled ADNI PET scans replaced with new re-worked images
The original raw and processed PET images for the BV visit FDG scan for subjects 128_S_1407 and 128_S_1408 contained reconstruction artifacts resulting from a problematic attenuation correction. When the 6m FDG scans were received for these subjects, QC determined mismatchs between BV and 6m scans bad enough to warrant re-processing of the BV scans.
