Summed Intrasubject Variability from 3 Different ROI Application Methods (n = 8)
| Method | Caudate nucleus | Putamen | Striatum | ICC |
|---|---|---|---|---|
| MD (BPND) | 19.4% ± 14.3% | 14.8% ± 6.0% | 11.9% ± 10.0% | 0.88 |
| MRD (BPND) | 16.4% ± 11.9% | 15.8% ± 11.7% | 14.6% ± 15.3%* | 0.90 |
| SVI (SBR) | 10.8% ± 10.2% | 0.90 |
↵* Calculated striatum = volume-weighted (caudate nucleus + putamen).
ICC = intraclass correlation coefficient.
