Qualitative measures for the images acquired using a diaphragmatic navigator with 5 mm gating window (Reference), 15 mm gating window with correction using the proposed motion compensation algorithm using 3, 5, and 15 bins, respectively.
Parameter (n=11) | Reference (Ref) | MC (3 bins) | MC (5 bins) | MC (15 bins) | MC (3 bins) vs. Ref | MC (5 bins) vs. Ref | MC (15 bins) vs. (3 bins) | MC (15 bins) vs. (5 bins) |
---|---|---|---|---|---|---|---|---|
RCA visual score | 3.4 ± 0.7 | 3.0±0.9 | 3.2±0.9 | 3.3 ± 0.6 | 0.12 | 0.5 | 0.37 | 1.00 |
LAD visual score | 2.6 ± 1.3 | 2.6±0.8 | 2.9±1.3 | 3.1 ± 0.8 | 1.00 | 0.53 | 0.06 | 1.00 |
LCX visual score | 2.7 ± 1.3 | 2.5±0.9 | 2.8±1.3 | 3.0 ± 1.0 | 0.68 | 1.00 | 0.06 | 0.62 |
Ref = Reference, MC = Motion-corrected, RCA = right coronary artery, LAD = left anterior descending, and LCX = left circumflex. All values are reported as mean ± one standard deviation. Statistically significant p-values reported in the last three columns, are in bold.
