To employ the scanners software computational capabilities and to simulate the complete measurement process without using expensive hyperpolarized gas, we developed the dedicated 1H MRI acquisition protocol using variable flip angle pulse sequence to simulate hyperpolarized magnetization decay. The protocol was used to study the effect of different space sampling ordering on images acquired with parallel acquisition techniques. Via the calculation of point-spread-function, the effects of the trajectories were quantitatively compared.
