Coronal parametric images of BPND, R1, and SUV (standardized uptake value) superimposed on X-CT images in [11C]NE40 and [11C](R)PK11195 studies. A SUV image was generated as a summation of tracer uptake during 40–60 min post-injection. The arrows indicate the peri-infarct region (penumbra). Mean tissue time-activity curves with standard deviations of each tracer on both frontal cortices are shown in different panels. Ipsilateral, lesion side; contralateral, non-lesion side
