Average and SD of CNR at Different Counts per Pixel in patients with degenerative nerve diseases (n = 22) and cerebrovascular diseases (n = 3)
| Parameter | 6 rotations | 5 rotations | 4 rotations | 3 rotations | 2 rotations | 1 rotation |
|---|---|---|---|---|---|---|
| Counts per pixel | 33.6 (±4.25) | 28.3 (±3.55) | 22.7 (±2.86) | 17.2 (±2.17) | 11.5 (±1.45) | 5.9 (±0.73) |
| Normalized CNR | 1.00 (±0.0) | 0.99 (±0.08) | 0.96 (±0.10) | 0.92 (±0.16) | 0.84 (±0.17)* | 0.56 (±0.25)* |
