A hospital CEO said AI could already replace “a great deal” of radiologists. Another called it “actually better than human beings.” Dr. A says both statements ignore the same inconvenient number: the false negative rate.In this episode, Dr. A breaks down the five hurdles that stand between today’s AI imaging tools and an actual radiologist replacement: radiologists trusting the technology enough to sign off on it, clinicians trusting an AI read without a second opinion, patients accepting an AI diagnosis, radiologists’ own resistance to being replaced, and the biggest fight of all: who takes on the liability when an AI misses a cancer. Running the clock on each hurdle, he lands on a prediction: real replacement doesn’t begin before January 2040.The claims are premature, they’re profitable for the hospitals making them, and none of the executives making them are radiologists.

We Also Cover
● For patients: An AI “read” on a mammogram or X-ray isn’t a diagnosis on its own, a radiologist’s second read is still the standard of care, and patients should ask whether a human physician reviewed their scan before acting on it.

● For clinicians: The technology’s real bottleneck isn’t accuracy alone, it’s trust, liability, and regulation. Current AI tools are decision-support, not a replacement for radiologist interpretation, no matter what a hospital CEO claims publicly.

●  System-level: No one has settled who’s liable when an AI misses a cancer, the software vendor, the hospital, or no one and that unresolved question, not the technology itself, is what’s actually slowing deployment.
