Abstract A 2D gradient-echo EPI is commonly employed for arterial spin labeling (ASL)
readout to achieve fast whole brain coverage measurements. However, such a readout
suffers from susceptibility artifacts induced by magnetic field inhomogeneities. To reduce
these susceptibility effects, single–shot spin-echo EPI was proposed to be used for
acquisitions in continuous ASL (CASL). To minimize functional and physiological variations,
a gradient-echo (GE)/spin-echo (SE) dual-echo EPI readout of the CASL sequence is …
