Evaluation of the SNR in the Echo-Shifted Pulse Sequence

Following recent interest in the echo-shifted (ES) pulse sequences, this study is concerned with the evaluation of the SNR of the ES signal. In particular, the SNR is evaluated as a function of number of TR periods the echo is shifted, N, and the flip angle. It was found that the SNR decreases as a hyperbolic function of N. The Ernst angle also decreases as a function of N.
