This work describes an implementation of free-breathing MR-fingerprinting (MRF) for quantitative imaging of the abdomen. The method relies on golden-angle radial sampling combined with compressed sensing and parallel imaging.
Comparison of MRF-derived parametric maps for imaging during free-breathing FB. Top row=gridding recon; bottom row=GRASP. From left to right: PD, T1, and T2 maps.
Effect
of reconstruction algorithm on standard deviation of calculated T1 and T2
values.
