The Spearman’s rank correlation coefficient for the results of the VSRAD analysis.

The results of the Spearman’s rank correlation coefficient are shown for (A): severity of voxel of interest (VOI) atrophy of artifact vs. the original image, (B): severity of voxel of interest (VOI) atrophy of U-Net motion-corrected vs. the original image and, (C): severity of voxel of interest (VOI) atrophy of Pix2Pix motion-corrected vs. the original image. The dotted line and white points plot show the relationship between the limits of agreement of the artifact image and the original image, and the solid line show the relationship between the limits of agreement of the motion-corrected image for U-Net or Pix2Pix and the original image. The rotation angle and k-space interval are plotted with 1°_30 pixel in black, 2°_20 pixel in red, and 3°_10 pixel in blue.
