New ASL Perfusion CBF by FreeSurfer ROI results now available in the Download section of the ADNI archive. The dataset can be found under MR imaging analysis.

Note on Scaling Correction of ASL Values: The summary values of ASL in brain regions have been scaled (i.e. divided by 10,000) to be consistent with the convention of expressing cerebral blood flow in units of mL/100mg/min.
