Temporal SNR estimation for various cleaning procedures and acquisition protocols. The boxplots show the distribution across 53 subjects. From the raw SNR results (2.A), it is clear that the cleaning procedure increases the SNR, while the reduced voxel volume and EPI acceleration decreases it. However, taking into account the increased number of timepoints (2.B), the statistical power for simple analyses applied to MB6 data is seen to be comparable to those from the standard acquisition. This is of great value because it means that the increase in statistical power due to the acceleration counters the loss in SNR caused by the increase in spatial resolution.
