Table 1 Mean-SNR and CNR of images reconstructed by diaphragmatic and respiratory self-gating navigators. The difference is not significant (p > 0.8).

From: Respiratory self-gated coronary MRI: A comparison between 2D spiral pencil beam and projection navigators

Reconstruction methods SNR CNR
Diaphragmatic navigator 36.38 ± 6.2 25.65 ± 6.02
Self-gating navigator 35.58 ± 5.6 24.88 ± 4.74
