Motion is a major challenge in MRI. Averaging multiple acquisitions of the same target can help suppress motion artifacts. However, combining multiple acquisitions with equal weighting can produce non-diagnostic image quality if one acquisition suffers from significantly more motion artifacts than the other acquisition. For this study, a framework for suppressing motion artifacts was developed by assigning higher weighting to the acquisition with less motion. The performance of the proposed strategy, called advanced signal combination (ASC), was evaluated in sagittal T2-weighted C-spine MRI obtained with number of acquisitions=2. ASC was found to suppress motion artifact while maintaining SNR.
