  • Activityref = reference region radioactivity/(ID/BW) 35–80 min after injection; ID/BW = injected dose per body weight; IM/BW = injected mass per body weight; Massref = reference region tracer mass concentration at 35–80 min after injection; SA = specific activity.

  • ROI values are 11C-(R)-PK11195 DVRs; all values are mean ± SD; P was calculated by 2-tailed t test.
