Measured artifact area and percentage reduction across conditions.
| Conditions | MAR off (mm2) | MAR on (mm2) | Percent reduction (%) |
|---|---|---|---|
| Overall | 317.39 ± 60.60 | 92.40 ± 55.27 | 70.9 |
| By exposure mode | |||
| Standard | 358.28 ± 40.28 | 137.83 ± 57.16 | 61.5 |
| Low-dose | 331.59 ± 50.78 | 87.66 ± 41.45 | 73.6 |
| Ultra-low-dose | 262.30 ± 44.01 | 51.72 ± 21.61 | 80.3 |
| By rod orientation | |||
| Horizontal | 357.82 ± 45.78 | 131.45 ± 50.26 | 63.3 |
| Vertical | 276.96 ± 44.53 | 53.36 ± 23.09 | 80.7 |
Measured artifact areas are presented as mean ± standard deviation. Percent reduction was calculated as: (artifact area of MAR off − artifact area of MAR on)/artifact area of MAR off × 100.
MAR metal artifact reduction, off deactivated, on activated.
