Example of tracing of posterior border of vertebrae for error change analysis. (A) Mid-sagittal slice of T2-weighted MRI from the Thorax Station for a single subject. The yellow represents the annotation of the posterior edge of the vertebral column on the T2. (B) Mid-sagittal slice of the DWI b = 0 s/mm2 prior to DisCo. The purple in this panel represents the annotation of the posterior edge of the vertebral column on the pre-DisCo DWI b = 0 s/mm2. (C) Mid-sagittal slice of DWI b = 0 s/mm2 after DisCo. The purple in this panel represents the annotation of the posterior edge of the vertebral column on the post-DisCo DWI b = 0 s/mm2. The average distance between the yellow and purple tracings (i.e., the error) decreases after application of DisCo. DisCo distortion correction.
