→Alibaba open-sources Damo Radar, a CT model that detects cancer and ~150 conditions
Alibaba's Damo Academy open-sourced Damo Radar, a vision-language model that reads abdominal contrast-enhanced CT scans. It covers 18 organs and identifies nearly 150 conditions including cancers. Tested on ~40,000 real-world exams, it hit an average AUC of 0.913. In a head-to-head with 26 radiologists, it outperformed 23 of them. With the model's help, radiologists cut missed diagnoses by 10% and reading time by over 30%. The study is in Science. The post doesn't disclose the open-source license, model size, or inference latency, so real-world cost is still unclear.

Alibaba open-sourced Damo Radar, a CT-reading model published in Science that beat 23 of 26 radiologists.

This one's worth opening because it pairs "published in Science" with "open-sourced." Damo Radar reads abdominal contrast-enhanced CTs across 18 organs and nearly 150 conditions, hitting an average AUC of 0.913 on ~40,000 real-world exams. In a head-to-head with 26 radiologists, it outperformed 23 of them; with the model's help, missed diagnoses dropped 10% and reading time fell over 30%.
I'd discount this on two fronts. First, the post doesn't disclose the license, model size, or inference latency — the three numbers that determine whether a hospital can actually deploy this. Second, an AUC of 0.913 is solid for medical imaging but not flawless, and the results are specific to contrast-enhanced abdominal CTs; don't assume the same number on non-contrast scans or other body regions.
Don't read this as "AI replacing radiologists." The more useful take: it's a validated assistive tool on one modality, and the open-source release lets the community figure out if it can be shrunk to deployable size and speed.
