| Respiratory efficiency (%) | Proximal sharpness (mm−1) | Mid sharpness (mm−1) | Proximal diameter (mm) | Mid diameter (mm) | |
|---|---|---|---|---|---|
| B2B-RMC (S.D.) | 99.7 (0.5) | 1.00 (0.14) | 1.01 (0.11) | 2.85 (0.38) | 2.85 (0.39) |
| nav-bSSFP (S.D.) | 44.0 (8.9) | 1.08 (0.11) | 1.05 (0.12) | 2.70 (0.34) | 2.80 (0.35) |
| P value | <.0001 | .15 | .24 | .026 | .60 |
Comparison of respiratory efficiency and both proximal and distal vessel sharpness and diameter obtained from images acquired with spiral B2B-RMC technique and nav-bSSFP technique. Proximal and mid results were obtained in 10 and 9 healthy subjects, respectively. All values are mean±S.D.
