One of samples included in the ADNI 2 APOE genotyping results may have been mislabeled and has been removed from the dataset. Those who downloaded the APOE results between January 25, 2012 and May 23,2012 should not use the results for the row containing RID=4014. New results for this subject will be posted after re-analysis.Continue reading...

A new AV45 analysis dataset is available. The previous AV45 dataset (November 2011) contains cortical and summary (SUVR) measures that were normalized by cerebellar grey matter. The new dataset (February 2012) is the same data and same subjects, but includes several additional reference region options (whole cerebellum, cerebellar grey matter, and brainstem) along with the non-normalized cortical regions. For more information [...]Continue reading...

All site 128 PIB scans have been re-reconstructed over the past several months. The new reconstruction code has a new scatter correction algorithm implemented, resulting in from some less to much less scatter being subtracted, particularly in the lower slices, e.g. those that include the normalizing region, cerebellar gray matter. There are 47 reworked PiB? [...]Continue reading...
