Figure 6:

Relative SNR in the myocardial and blood, and blood-myocardium CNR for 12 healthy volunteers at peak-systole and end-diastole (mean ± standard deviation). Spiral in-out and EPI SNR values are shown relative to reference Cartesian imaging. Gray dots show individual measurements. High variance in SNR for EPI is due to corruption by motion/flow artifact. The dotted line represents theoretical SNR (by $\sqrt{T_{sampling}}$).
