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. Both “raw” and “pre-processed” FDG images for these two subjects downloaded before 2/12/2008 should be deleted and replaced with the new images sets, as the re-worked images sets were approved and “pre-processed” images uploaded to LONI on 2/11/2008.

Corrected BV FDG image sets for subject 128_S_1407 have series UID S41093. The corrected raw images have image UID I90029. (Original raw images NOT TO BE USED have image UID I77122)

Corrected BV FDG image sets for subject 128_S_1408 have series UID S42724. The corrected raw images have image UID I90030. (Original raw images NOT TO BE USED have image UID I82093)

The original raw and processed PET images for the 12m visit PIB scan on subject 128_S_0188 contained time framing errors (frames were not from 50-70 min post-injection). Both raw and processed PET PIB images for this subject downloaded before 12/18/2007 should be deleted.

Corrected 12m PIB images for subject 128_S_0188 have series UID S35089. The corrected raw images have image UID I85224. (Original raw images NOT TO BE USED have image UID I60256)

Data Recall Advisory

From time to time, our PET Quality Control process identifies data as faulty that have already been posted and downloaded by users. We are not able to notify individual investigators of these problems. Therefore, any investigators working with PET data should regularly check the following site for notification of faulty data, and this data should be removed from all analyses until it has been corrected and reposted.
