Perfusion weighted imaging (PWI) is not incorporated
into routinely abdominal imaging due to the need for
additional contrast injection and acquisition time. We
have developed a novel acquisition and reconstruction
method called GRASP (GRASP: Golden-angle RAdial Sparse
Parallel) whereby data is acquired continuously in
free-breathing and retrospectively reconstructed with
flexible temporal resolution. In this study we have
shown that high temporal GRASP reconstruction can be
used for PWI to accurately measure kidney function
(MR-GFR) as compared with the Cartesian scheme.
Furthermore images reconstructed with different temporal
resolution from a single acquisition can be used for
morphologic evaluation.
