Figure 2From: Accelerated 4D flow imaging with variable-density cartesian undersampling and parallel imaging reconstructionFlow images obtained with a) R=1 (full), b) R=6 VD-PDD and SPIRIT with improved initial solution (M1), and c) R=6 VD-PDD with reduced undersampling and SPIRIT with improved initial solution (M2). d-e) show representative flow-waveforms of AA and DA with full data, M1 and M2.Back to article page
