DOI: 10.1002/mrm.28713
Abstract: Whole‐heart MRA techniques typically target predetermined motion states, address cardiac and respiratory dynamics independently, and require either complex planning or computationally demanding reconstructions. In contrast, we developed a fast data‐driven reconstruction algorithm with minimal physiological… read more here.
