The in-vivo SNR for DENSE MRI was evaluated for 32 channel cardiac coils compared to standard 5 and 6 channel coils at 1.5 and 3T. On average, the 32 channel coils provided 50% higher SNR. The SNR improvement was more pronounced at 3T than at 1.5T, and closest to the chest wall. The higher SNR provides the opportunity for DENSE imaging in a longer portion of the cardiac cycle.
