Alibaba DAMO Academy released DAMO LiON, a liver cancer detection model:

Improved architecture captures both lesion–whole-liver relationships and the local texture/boundary details critical for small tumors;
Handles hard cases — fatty liver, cirrhosis, post-surgical livers — and excels at detecting liver metastases often overlooked by radiologists;
Identifies malignant tumors more accurately than radiologists: AI assistance cut reading time by 27%, raised sensitivity for malignant tumors by 11.5%, and brought junior doctors to senior-level performance;
Deployed in a hospital for two months, it caught 15 previously missed liver metastases across 10,000+ patients, changing their treatment plans.
