The Paradox of Medical AI ImplementationValidated imaging AI stays out of routine care while unproven LLMs are adopted fast and make dangerous triage errors.
Why does demonstrated diagnostic capability keep outrunning delivered care — and can deployment close the gap without opaque errors and unequal access?
Diagnostic parity keeps arriving in trials ahead of deployment, liability frameworks, and reimbursement; how much of the remaining gap is institutional rather than technical is the live dispute.

The deployment paradox sharpened: Topol documents validated imaging AI staying out of routine care while unproven LLMs spread fast — and a randomized trial in Pakistan showed LLM assistance raising physician diagnostic scores from 43% to 71%, but only for clinicians trained to use it.

Those with LLM access achieved a mean diagnostic reasoning score of 71.4% versus 42.6% with conventional resources alone
