| Diameter | 1.3 (0.2) | 1.3 (0.2) | 1.4 (0.2) | 1.4 (0.1) |
| Percent stenosis (%) | 52.3 (9.5) | 53.2 (6.8) | 49.7 (6.4) | 49.9 (5.2) |
| 75% plaque | ||||
| Diameter | 0.7 (0.1) | 0.7 (0.1) | 0.8 (0.1) | 0.7 (0.1) |
| Percent stenosis (%) | 72.5 (5.8) | 73.0 (3.8) | 70.6 (4.6) | 73.1 (2.9) |
The diameter and percent stenosis values are presented as mean (standard deviation). HIR, hybrid iterative reconstruction; MBIR, model based iterative reconstruction; DLR, deep learning-based reconstruction.
