The proposed technique, phase-contrast MRI (PC-MRI) technique with hybrid one- and two-sided flow-encoding and velocity spectrum de-aliasing (HOTDEAL) using low spatial resolution reference four-point PC-MRI for accelerated blood flow and velocity measurement, is a novel M1-space (gradient first moment space) under-sampling technique for accurate Fourier velocity spectra separation.
