Our op-ed @nytopinion.nytimes.com addresses the surprising results of recent medical studies that showed A.I. alone outperformed physicians using A.I. With @rajpurkar.bsky.social
Here is a summary Table, an overview, and a gift link to the op-ed

Our new Harvard/Stanford study out today in Nature Medicine! Our results show language models, while strong at medical exams, stumble when they need to gather patient information through natural conversation - a key finding as healthcare explores AI integration.

How to solve? Enter CRAFT-MD.

If developers are coming to you with a model claiming to perform great report generation on chest X-rays, ask them to do a fair comparison on ReXrank. Let's separate the hype from the reality.
ReXrank: Radiology Report Generation Leaderboard
Open-source leaderboard for comparing and benchmarking AI models in radiology report generation.

We have now launched a competition called ReXrank to track progress.
With Gradient Health, we have collaborated to produce the now the largest and cleanest private dataset to evaluate models.

I don't think it's widely clear to the #RadiologyAI community just how poorly GPT-4V compares with the top report generation models on chest X-rays, like MedVersa or MAIRA-2.

It's clear we need a way to track progress.

Please welcome MedAutoCorrect = Spelling check for medical imaging reports.
"Model leverages image-conditioned data processing to enhance the accuracy of medical report generation."
It seems simple, yet at the same time, it is incredibly advanced.

Includes a cameo by @mattlungrenmd.bsky.social , as the course covers an expert perspective on real-world AI in radiology.

Most importantly, it's curated to be very accessible and approachable, requiring no mathematical background. I walk you through the science. And it's short :) Here's a teaser for one of the courses – this is on Medical Image Interpretation.

I've curated lessons using real-world research examples, where I go through classic problem formulations and how they have been approached by world-class teams. For some case studies, I've used examples from my own research to give you insight into the back story surrounding cutting-edge research.

Delighted to launch 2 new short courses on AI for Medicine, now open for registration at Harvard Medical School online learning platform!

No FDA approved Ai for level 3 and 4 AI!

If a machine makes the same mistake again and again, it's precise. but that's not what we want. We also need accurate AI.
