Because of the development of compressed sensing (CS) technology in both spatial and temporal related data acquisition, four-dimensional flow MRI scan can be accomplished in a clinically acceptable time. We evaluated the highly accelerated four-dimensional flow magnetic resonance imaging in portal system hemodynamics studies with Compressed SENSE (CS-SENSE). There was no statistically significant difference in flow velocity, volume rate, axial-WSS of portal system when compared among different CS, measurements from the two observers matched well with each other.
