+[07/20/2018] First release of DeepLesion.
+[07/27/2018] We re-zipped the images and replaced the old zips in Images_png. The files in old and new zips are the same in total except that every new zip file contains several independent folders and can be unzipped alone. Readme and FAQ are updated. We also added a folder "Key_slice_examples" to help users understand the dataset at a glance.
+[07/30/2018] The link to our GitHub page is added in readme, which includes a project showing how to train a lesion detector using DeepLesion.
+[09/05/2018] batch_download_zips.py is added to download all 56 zip files automatically.
+[05/13/2019] Address of the semantic labels (tags) for the lesions is addeed in readme and FAQ.
