a) Online leaderboard at the completion of the challenge (December 2019). Three quantitative metrics are provided for R=4 and R=8 for both image contrasts on the webpage, along with a selection of reconstructed images. A short description of the reconstruction approach used, together with links to a corresponding paper or code repository, are also shown if the submitting groups provide this information. b) SSIM scores of the challenge submissions for each track. As expected, there is a substantial difference in overall SSIM values between the multi-coil and the single-coil tracks.
