In this study we evaluate the importance of increased
temporal resolution when analysing resting state
networks. Furthermore, we evaluate the performance of
two alternative approaches to obtain 3-fold acceleration
in terms of temporal resolution in respect to standard
multi-slice 2D-EPI: 3D-EPI-CAIPI and SMS-EPI. Both
accelerated sequences offered improved statistical power
in the RSN detection. Similar RSNs were detected with
3D-EPI-CAIPI and SMS-EPI and both could detect
additional networks compared to standard 2D-EPI.
