ISMRM Fetal cardiac volume recon
Fetal cardiac volume reconstruction from motion-corrected multi-slice dynamic MRI
Motion is a significant challenge in fetal cardiac MRI. Multi-slice 2D dynamic MR data was used to reconstruct high-temporal resolution real-time images to be combined in time as 2D cine images and then in space as volumes with full coverage of the heart. Retrospective, image-based post-processing (motion correction, outlier rejection) was used to improve image quality in the presence of intra- and inter-slice motion. Reconstructed multi-slice cine images depict the complex anatomy of the fetal heart across the cardiac cycle and preliminary volume reconstructions allow multiple views to be visualised.
