Preliminary evaluation of the feasibility to perform resting state BOLD fMRI at a low field (0.5 T) MR scanners equipped with a high-performance gradient system by investing the detection capability of RSNs at lower field strengths. There was an overall deterioration in the number of detected regions within all RSNs as the tSNR decreased. However, the 0.5 Evry system that will be used for experimental studies offer a better SNR efficiency than the modelled cases considered here suggesting reasonable capability in extracting RSNs that can potentially provide clinical utility.
