The short version

  • Each has a real cost: Aidoc the clearances are for triage and notification in the CADt category, so the software may reorder a worklist but may not deliver a diagnosis or replace a read, and business cases built on reduced radiologist workload do not survive contact with the regulatory wording.; Koa Health psychPlus acquired Koa Health in June 2026, so buyers are now contracting with the technology arm of an American psychiatry provider group rather than a European digital health company, and roadmap, data residency and European product investment should all be re-examined before renewal.
  • They diverge on capability: Aidoc covers Triage and notification, Koa Health covers Stepped care triage.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aidoc

  • The clearances are for triage and notification in the CADt category, so the software may reorder a worklist but may not deliver a diagnosis or replace a read, and business cases built on reduced radiologist workload do not survive contact with the regulatory wording.
  • Triage algorithms are tuned for sensitivity, so false positives are routine, and each one interrupts a radiologist. Sites that do not measure positive predictive value in their own case mix see clinician trust erode within months.
  • Pricing is per algorithm and per study volume with no published rate card, so the cost of a multi algorithm deployment escalates sharply and cannot be benchmarked before a sales conversation.
  • The clinical benefit accrues to stroke, trauma and cardiology service lines while the cost usually lands in the radiology or IT budget, which makes internal funding harder than the return on investment slides suggest.
  • Performance depends on scanner protocols and reconstruction settings, so results validated at one site do not transfer, and each deployment needs local validation work that is rarely budgeted for.

Koa Health

  • PsychPlus acquired Koa Health in June 2026, so buyers are now contracting with the technology arm of an American psychiatry provider group rather than a European digital health company, and roadmap, data residency and European product investment should all be re-examined before renewal.
  • Stepped care only produces savings when triage is accurate, and members routed to a self guided module when they believe they need a therapist commonly disengage entirely, which a utilisation report records as low engagement rather than as a triage failure.
  • Pricing is per employee or per member per month across the eligible population, so an employer with modest engagement pays for everyone in order to serve a minority.
  • Clinician availability and language coverage differ substantially by country, so a multinational contract that reads as one global standard delivers a materially different experience in secondary markets.
  • Koa competes against much larger and better funded benefits vendors in the United States, and the acquisition does not change the fact that its brand recognition with American benefits consultants is low, which affects broker driven shortlists.

Answered from the vendors’ own pages

Aidoc: Is Aidoc FDA cleared?

Yes, it holds multiple 510(k) clearances, but they are for computer aided triage and notification. It may prioritise a worklist and notify a team. It may not provide a diagnostic interpretation or replace a radiologist read.

Koa Health: Is Koa Health still operating?

Yes. PsychPlus acquired it in June 2026 and the brand and platform continue. It is not a shutdown, but the ownership and clinical direction have changed.

Aidoc: Does it reduce radiologist workload?

No. Every study still needs a full read. The benefit is in the order studies are read and how quickly a receiving specialty is activated, not in reading fewer studies.

Koa Health: Who buys Koa Health?

Employers, health plans and health systems. It is not sold direct to individuals.

Aidoc: Can I run other vendors AI through it?

Yes, that is what the aiOS platform layer is for, and for health systems with several AI vendors it is often the main reason to buy Aidoc at all.

Koa Health: How is it priced?

Per employee or per member per month, quoted rather than published, with the rate depending on which steps of the care ladder are in scope.

Aidoc: Is pricing published?

No. It is quoted per algorithm and by annual study volume, and enterprise bundles are negotiated case by case.

Koa Health: Does it provide access to psychiatrists?

Clinical access is included in the higher tiers, and the PsychPlus acquisition adds psychiatry provider capacity in the United States. Confirm what your specific contract covers.
