Motivation: Concern over gadolinium contrast injections for research purposes limits in vivo testing of new imaging methods. An in-silica optimization strategy is needed when developing advanced reconstructions in the setting of free-breathing abdominal DCE MRI.
Goal(s): Demonstrate a framework for testing performance of different reconstructions.
Approach: A publicly available DRO was used to generate simulated free-breathing abdominal DCE k-space data. Data was then reconstructed using different reconstruction settings for MOCCO and SENSE.
Results: This approach allowed head-to-head comparisons of different reconstruction methods as well as comparison with the ground truth data used to generate the DRO.
Impact: The proposed testing approach allows researchers to test numerous combinations of acquisitions and reconstructions while having ground truth as a benchmark.
