List of Medical (Imaging) Datasets

I maintain this list mostly as a personal braindump of interesting medical datasets, with a focus on medical imaging.
Rather than try to group / cluster datasets, I'm going to try to maintain a set of keywords for each.
See commit log for a list of additions over time.

Please feel free to contribute!

Disclaimer: please remember to solve real clinical problems ☺
