This study investigates the potential for interleaving a
DCE-MRI experiment with the acquisition of a high
temporal resolution AIF using a radial projection-based
approach. A mouse tail phantom was scanned with two
slice packs: one for the AIF (radial, single slice) and
one for the DCE experiment (Cartesian, multi-slice). By
interleaving these acquisitions, we maintain a high
temporal resolution for the AIF, and sufficient spatial
and temporal resolutions for the DCE experiment. This
technique is expected to improve the accuracy of fitted
model parameters as the AIF is specific to the
individual study.
