 ## Note
-In accordance with the license, CADS does not redistribute HaN-Seg images or any derivative works. We are currently working on obtaining permission from the dataset authors to share example images with our segmentations.
+We did not include the original GT annotations for spinal cord from HaN-Seg. Since other datasets in CADS cover a larger field of view where the spinal cord extends below the head-and-neck, we generated our own spinal cord segmentations on Han-Seg images to ensure consistency across CADS.
