There's a lot to unpack here! In the USA, the ABR regulates human radiologists via board certification. Medical technology is traditionally regulated by the 510K, PMA, and de novo pathways at the FDA. Of course, these products still have to demonstrate value in order for major stakeholders (hospitals, radiology practices) to purchase them. And using these products does not absolve the ordering doctor, the radiologist, or the hospital of legal liability for misdiagnosis. In fact, IANAL and this is a somewhat novel area of the law, but any AI product that functions as a drop-in replacement for a radiologist might be held liable for misdiagnosis that leads to harm. These liabilities could become quite large for a product deployed at scale (a single misdiagnosis causing death can lead to a settlement in excess of 10 million dollars). In summary, there's quite a bit more to the issue than simple "gatekeeping." It might be appealing to blame radiologists for these issues, but there's a much larger system at work that's designed to ensure quality and safety for patients. This is not AdTech - lives are at stake and people can get hurt. Now, this definitely comes with a cost to innovation, but it's going to take more than just a few MD's to reinvent the economics and law of computers practicing medicine on people.
