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 about calculating SUVRs and cutoffs, see the Jagust – AV45 Analysis (Non-normalized) Methods document or email Susan Landau.
