A novel framework that minimizes eddy current mismatch between tag and control acquisitions in velocity-selective (VS) arterial spin labeling is introduced. The framework is based on minimizing the 0th-order gradient moment in the presence of eddy currents and is applicable to any VS module design, without suffering a time penalty in module duration. Simulation and empirical data are presented and demonstrate reductions in eddy current artifacts in both phantom and in vivo data.
