Compared to coil-by-coil reconstructions, Direct Virtual Coil (DVC) parallel imaging reconstructions improve computational efficiency for high channel count coil arrays by only synthesizing unacquired data for one virtual coil instead of synthesizing a separate dataset for each physical coil. In this study, image quality is compared between coil-by-coil and DVC parallel imaging reconstructions in the context of contrast-enhanced liver imaging. Results showed no significant difference in the image quality achieved by the two reconstruction methods.
