4D flow MRI provides comprehensive assessment of cardiovascular hemodynamics. However, the current clinical usage of standard 4D flow MRI is hindered by long scan times and extensive, time-consuming post-processing such as eddy current corrections, noise masking, and 3D vessel segmentation. We seek to address this by developing a fully automated image reconstruction and post-processing pipeline for highly-accelerated aortic 4D flow MRI (R=5.7-10.2). The fully automated pipeline was shown to provide good-to-excellent agreement in quantitative and hemodynamic measures to conventional 4D flow MRI (GRAPPA, R=2) with manual post-processing. Additionally, the pipeline only requires <10 minutes compared to 20 minutes manually.
