Quality parameters v expert assessment (p values, Wilcoxon test comparing with “poor” scan values)
| Excellent | Acceptable | Poor | |
|---|---|---|---|
| SNR (dB) (n = 36) | 40.2 (9.0) (0.04) (n = 4) | 35.4 (5.5) (0.02) (n = 19) | 30.0 (6.1) (n = 13) |
| SS (n = 45) | 6.11 (1.54) (0.002) (n = 7) | 5.53 (1.31) (<0.001) (n = 24) | 3.21 (1.63) (n = 14) |
| QI (n = 63) | 34.6 (6.9) (<0.001) (n = 9) | 24.5 (6.4) (<0.001) (n = 32) | 11.9 (2.9) (n = 22) |
Only QI showed a significant difference between excellent and acceptable images (p = 0.001).
