Report generated on data submitted as of: 15 September 2014.

Note: Ipsilateral and contralateral refer to DAT tracer uptake and are defined in relation to the predominant side of clinical symptoms. For PD subjects with symmetrical presentation, ipsilateral and contralateral sides are defined as the mean of the left and right values.
