Notes

The current publication reports 1,048 wrist radiographs from 388 patients across six medical centers. Pixel-level instance segmentation is available for 618 images and Sharp/van der Heijde bone-erosion scores are available for 800 images. Segmentation masks are distributed as 14-channel NPY arrays representing individual wrist bones. Wrist is represented as 'other' because the current anatomy enum does not contain a wrist value.
