Automated streaking artifact suppression for multi-echo radial abdominal data compatible with advanced reconstruction techniques

Motivation: Streaking artifacts, often emanating from the arms, are a major issue in radial abdominal imaging. Solutions typically consist of estimating coil sensitivity maps that suppress artifacts and often ignore phase information Goal(s): To suppress streaking artifacts with a method that will not disrupt phase in multi-echo data and be easily incorporated into existing reconstruction algorithms. Approach: Modifying an existing coil-domain method that can be applied directly to k-space or coil sensitivity maps for reconstruction of multi-echo data. Results: The proposed method out-performed existing artifact suppression techniques and improved the reconstruction of water and fat images coming from multi-echo data. Impact: The proposed destreaking method was demonstrated to be equivalent when applied to multi-coil images, multi-coil k-space, or coil sensitivity maps, providing flexibility when being incorporated into existing reconstruction algorithms. It out-performed existing techniques and improved the reconstruction of multi-echo data.
