@EricTopol @LancetDigitalH @curtlanglotz Thanks for the shout out, Eric. This is part of our work through the Topol Digital Fellowship, focused on making medical imaging reports more accessible for patients. Good progress so far, with more to come.

When the LLM rewrites the radiology report, patient understanding is increased and clinical accuracy is maintained. @LancetDigitalH @curtlanglotz @smrabd thelancet.com/journals/landi…

Ever tried reading your own CT or MRI scan report? Found it confusing? AI can rewrite it into plain language. In 38 studies, patients say it helps and clinicians say it’s accurate but ~1% had significant errors. The future of radiology communication? Out today @LancetDigitalH

The annual @radiology_rsna Top Publications list is always a highlight! Thrilled two of our papers are recognized this year 😊 🔗 doi.org/10.1148/radiol… AI in cardiac CT/MRI 🔗 doi.org/10.1148/radiol… Air pollution and fibrosis Looking forward to another wonderful year ahead!✨

Tremamunno et al show that ultra–high-resolution photon-counting CT (PCD-CT) detects more plaques but less stenosis than EID-CT, reclassifying >50% of patients to lower CAD-RADS. PCD-CT doesn’t just sharpen images—it changes interpretation. doi.org/10.1016/j.jcct…

What's the best AI model for medical advice? Most evals focus on accuracy; we benchmarked harm First, do NOHARM: 100 real cases, 12k+ expert ratings Preprint: arxiv.org/abs/2512.01241 Interactive leaderboard: bench.arise-ai.org

Proud to share First Do NOHARM, the first medical AI benchmark created and named in the spirit of medicine's foundational principle. 2/3 of US clinicians and millions of patients use AI every day. But how often does AI advice actually harm patients? We built NOHARM to find out. Using 100 real clinical cases across 10 specialties, with 12,747 expert annotations, we measured harm frequency and severity from 31 LLMs. What we found: - Severe harm occurs in up to 1 of 5 of cases - 77% of serious errors are sins of omission, failing to recommend critical actions - Existing AI benchmarks poorly predict clinical safety - Multi-agent systems can substantially reduce harm - The best models outperform human generalist physicians on safety The uncomfortable truth: models tuned for caution can paradoxically increase harm by missing essential recommendations. And doing nothing is worse than every AI we tested. As AI moves from documentation to clinical decisions, we need explicit safety measurement, not just accuracy scores. Honored to have been part of this groundbreaking work by our ARiSE Healthcare Network team at @StanfordMed and @harvardmed, which is just the beginning, as we develop a full suite of realistic clinical benchmarks we are calling MAST: Medical AI Superintelligence Test that medical AI developers can use to evaluate the real-world clinical performance and safety of their own models. Reach out if you are interested in testing your model! I particularly enjoyed building this beautiful interactive leaderboard with @DavidWuMDPhD, Ethan Goh, Joel Koh, Emily Tat, Augustine Chemparathy, Adi Badhwar and Kanav Chopra, which you can use to explore our results, comparing solo models as well as multi-agent teams across many harm and safety metrics. Deeply grateful to @jonc101x for his mentorship and for making this work possible. Leaderboard and paper: bench.arise-ai.org
