^aAll protocols, if applicable, acquired with b = 1000 s/mm²

^bGaps between slices of 4.5 mm for 20 slices, and 9.0 mm for 10 slices were used

^cScan time matched to that of rs-EPI SMC to maintain signal comparison between sequences

Scan time without additional ACS data and preparation for SMC (same TR) = 2:56 min/1:28 min
