The inter-subject variability (CV) in baseline BPND before and after motion correction (MC)
| Region (ROI size) | SN (0.3 cm3) | GP (0.8 cm3) | VST (1.0 cm3) | CD (2.8 cm3) | PU (4.2 cm3) | TH (5.3 cm3) |
|---|---|---|---|---|---|---|
| CV before MCa | 0.3699 | 0.3405 | 0.6345 | 0.2825 | 0.2627 | 0.5172 |
| CV after FBFb | 0.1785 | 0.7411 | 0.2857 | 0.1173 | 0.0848 | 0.1630 |
| CV after GIR | 0.1523 | 0.0896 | 0.1822 | 0.0962 | 0.0772 | 0.1606 |
Unrealistically large V T values due to unsuccessful convergence in 2TC kinetic parameter estimation as a result of uncorrected motion artefacts were removed. ROI sizes are given in cubic centimetres
aTwo outlier values removed
bThree outlier values removed
