Alibaba's RADAR AI reads abdominal CT scans; performance claims still need independent testing
Alibaba has announced RADAR, an open AI model trained on more than 400,000 contrast-enhanced abdominal CT scans, using existing clinical reports. The developers claim specialist-level performance, but that claim still needs independent testing.

What the research shows
The article describes RADAR, a vision-language model for contrast-enhanced abdominal CT scans. According to the company, it was trained on more than 400,000 scans and learned from clinical reports already written by doctors, without people manually labeling the images. The developers also state that the model performs at specialist level. That is their own claim, and the text does not report any independent study confirming it.
The most notable aspect is the training method: using radiology reports that already exist, rather than hand-made annotations, may reduce the work needed to build AI systems for radiology. Even so, a model trained on a large dataset must be evaluated in other hospitals, with other equipment and other patient groups, before anyone knows whether its results hold up in practice.
What it means
The announcement shows a promising way to train AI on medical images using reports that already exist. It is still unknown whether RADAR is as accurate as claimed, where it makes mistakes, and how it would perform in health services different from the ones that supplied its data.
How to read it with care
An AI tool for scans does not replace a doctor's assessment or a radiologist's interpretation. If you have questions about an imaging test, talk to your doctor or another qualified health professional..
