Default mode network functional connectivity in BOLD and pCASL scans at both scanning locations. Functional connectivity maps with PCC as the seed region are shown for each subject at each location for BOLD (a) and pCASL (b) resting state scans. Inter- and intra-subject variability expressed as mean standard deviations, intraclass correlation coefficients (ICC) and Dice Similarity Coefficients (DSC) for BOLD (c) and pCASL (d) resting state scans are shown for the DMN subregions MPFC, PCC, LLP, and RLP as the seed regions and the PCC, LLP, RLP, ACC, and left and right insula as the ROIs. Inter- and intra-subject variability were not significantly different for both BOLD and pCASL scans. Both the BOLD and pCASL functional connectivity maps showed high intraclass correlation in at least one DMN pathway, but the pathways showing the highest ICC values differed between the two scan sequences
