Respiratory motion remains a major challenge in clinical abdominal MRI. Recent technical advances using continuous radial imaging during free-breathing and motion-resolved compressed sensing-based image reconstruction have demonstrated improvements in motion robustness over conventional motion-gated or motion-corrected techniques, but they were not validated for liver imaging. This work implemented extra-dimensional (XD) reconstruction for free-breathing RadialLAVA acquisitions and compared it against conventional breath-held CartesianLAVA. We demonstrate that the XD technique matches that, and in some instances, is superior to that of standard breath-hold technique in terms of overall image quality in the evaluation of post-contrast liver images.
