Continuous table movement MRI is an emerging technique for a variety of clinical applications. The achievable acceleration with parallel imaging, however, is not yet sufficient to scan an extended FOV in a single breath-hold. Radial scanning in combination with innovative iterative image reconstruction and joint coil estimation promises significantly higher acceleration factors. This method was implemented for moving table abdominal MRI in a single breath-hold and was evaluated in 5 healthy volunteers. It was proven that highly undersampled radial images can be reconstructed with very little streaking artifacts which justifies further investigation in volunteers and patients.
