This feels like it was done for the clicks and not actual research. There are plenty of AI startups in the radiology game, GPT-4V isn't free - so why is that the one being tested?
Run research on models that are actually trained to solve these issues, that is relevant research
Just as an example, Viz.ai applied[1] and received FDA clearance/approval for their model in hospitals.
Have OpenAI ever submitted a request for use of GPT-4V? Whats next, try autopilot driving with GPT-4V?
