Figure 4.

Comparison of motion-averaged NUFFT reconstruction using all the acquired spokes, 4D dynamic images reconstructed using GRASP-Pro (5 spokes each temporal frame) and 4D respiratory-resolved images reconstructed using XD-GRASP (162 spokes each respiratory phase) in non-DCE dataset 1. Both expiratory and inspiratory images are displayed for GRASP-Pro and XD-GRASP reconstruction. Compared to motion-averaged reconstruction, both GRASP-Pro and XD-GRASP reconstruction yielded improved image sharpness as indicated by the better delineated vessel-tissue boundaries.
