Table 3.
Ratios between striatum as well as caudate nucleus and putamen, shown by median (min;max).

| SBRcalc | 0.82 (0.75; 1.00) | 0.65 (0.53; 0.73) | 0.81 (0.45; 0.95) |

| SBRcalc | 0.96 (0.71; 0.99) | 0.94 (0.65; 0.73) | 0.81 (0.45; 0.95) |
| BPND | 0.95 (0.79; 0.99) | 0.93 (0.58; 1.19) | 0.73 (0.58; 0.82) |

Ratios between striatum is computed from the lowest value divided by the highest value of left and right striatum; thus 1.00 indicating complete symmetry and lesser/higher values indicating increasing asymmetry. Putamen/caudate nucleus ratio for both left and right striatum. Specific binding ratio (SBRcalc) calculated from the corrected data of the 3 h p.i.images.
BPND non-displaceable binding potential extracted from SRTM, LS low score patients, HS High score patients.
