Among the various scan acceleration techniques available to Phase-Contrast(PC)-MRI, Compressed sensing (CS)has recently been demonstrated. In this work, it It is hypothesized that reconstruction accuracy with respect to object phase depends on inflow contrast. Using 2D and 3D in-vivo flow data acquired in the aortic arch it is demonstrated that reconstruction error
