AI Led To an Increase In Radiologists, Not a Decrease

Despite predictions that AI would replace radiologists, healthcare systems worldwide are hiring more of them because AI tools enhance their work, create new oversight tasks, and increase imaging volumes rather than reducing workloads. "Put all that together with the context of an aging population and growing demand for imaging of all kinds, and you can see why Offiah and the Royal College of Radiologists are concerned about a shortage of radiologists, not their displacement," writes Financial Times authors John Burn-Murdoch and Sarah O'Connor. Amaka Offiah, who is a consultant pediatric radiologist and a professor in pediatric musculoskeletal imaging at the University of Sheffield in the UK, makes a prediction of her own: "AI will assist radiologists, but will not replace them. I could even dare to say: will never replace them." From the report: [A]lmost all of the AI tools in use by healthcare providers today are being used by radiologists, not instead of them. The tools keep getting better, and now match or outperform experienced radiologists even after factoring in false positives or negatives, but the fact that both human and AI remain fallible means it makes far more sense to pair them up than for one to replace the other. Two pairs of eyes can come to a quicker and more accurate judgment, one spotting or correcting something the other missed. And in high-stakes settings where the costs of a mistake can be astronomical, the downside risk from an error by a fully autonomous AI radiologist is huge. "I find this a fascinating demonstration of why even if AI really can do some of the most high-value parts of someone's job, it doesn't mean displacement (even of those few tasks let alone the job as a whole) is inevitable," concludes John. "Though I also can't help noticing a parallel to driverless cars, which were simply too risky to ever go fully autonomous until they weren't." Sarah added: "I think the story of radiologists should be a reminder to technologists not to make sweeping assertions about the future of professions they don't intimately understand. If we had indeed stopped training radiologists in 2016, we'd be in a real mess today."
