ROIs and BPND images. A) Striatal (top) and midbrain (bottom) ROIs used for extracting BPND. B) Example of one subject’s [18F]fallypride BPND image in native PET space. BPND was highest in the striatum (top) and the midbrain (bottom). Note, scaling is different in the bottom figure to allow better visualization of the midbrain.
