The baseline PET FDG scan for ADNI subject 109_S_1343 has been determined to be the wrong subject. At the time of the 6m PET scan on 109_S_1343, the PET FDG image sets were found not to match, i.e. they were from different subjects. The site has determined that it was the baseline scan that was in error. The baseline FDG scan for this subject has been processed and reuploaded. All investigators will need to replace the baseline PET for this subject in their analyses. (See also the November PET Scan issues file)
