The short version

  • Each has a real cost: Ambra Health intelerad now owns Ambra and ambrahealth.com redirects to Intelerad client support, so a buyer is committing to the Intelerad portfolio roadmap and should get written positioning on Ambra versus Intelerad own cloud PACS before signing.; Signant Health no pricing is published, and the software licence is a minority of the real bill once instrument licensing, translations, device provisioning and services are added, so early budget estimates are routinely too low.
  • They diverge on capability: Ambra Health covers Image exchange, Signant Health covers eCOA and ePRO.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Ambra Health

  • A trauma centre that receives transfers from regional hospitals and needs outside CT studies readable before the patient arrives, not after a disc is walked innot Signant Health
  • An oncology programme collecting outside imaging for multidisciplinary tumour board review from dozens of referring practicesnot Signant Health
  • A clinical research organisation routing de identified trial imaging from many sites to one central reading facilitynot Signant Health
  • A health system trying to eliminate the CD import desk by giving patients and referring practices a direct upload portalnot Signant Health

Signant Health

  • A central nervous system or psychiatry trial where the primary endpoint is a rated scale and rater consistency decides the readoutnot Ambra Health
  • A global study needing an outcome instrument translated and linguistically validated across a dozen languagesnot Ambra Health
  • A decentralised or hybrid protocol combining televisits, eConsent and at-home patient reported outcomesnot Ambra Health
  • A sponsor consolidating separate eCOA, eConsent and randomisation vendors onto one platform to cut reconciliation worknot Ambra Health

Where each one falls short

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

Ambra Health

  • Intelerad now owns Ambra and ambrahealth.com redirects to Intelerad client support, so a buyer is committing to the Intelerad portfolio roadmap and should get written positioning on Ambra versus Intelerad own cloud PACS before signing.
  • Ambra is built for cross organisation exchange, not for high volume in department diagnostic reading, so a radiology group that expects it to replace a departmental PACS finds the reading ergonomics and hanging protocols thinner than a dedicated PACS client.
  • Pricing scales with study volume and stored capacity, so a health system that turns on patient upload broadly sees storage grow from low value outside studies it never intended to retain, and the renewal reflects that.
  • Identity reconciliation of studies arriving with foreign patient identifiers still needs human review at volume, and sites that budget for zero touch matching end up staffing an imaging records queue.
  • Adoption depends on referring practices actually using the portal, and the vendor cannot make that happen, so image exchange projects frequently stall at the outreach and change management step rather than at the technology.

Signant Health

  • No pricing is published, and the software licence is a minority of the real bill once instrument licensing, translations, device provisioning and services are added, so early budget estimates are routinely too low.
  • Linguistic validation is charged per instrument per language and is on the critical path to first patient in, so adding a country late in start-up produces both a cost and a schedule hit.
  • Provisioned participant devices bring logistics, replacement, shipping and cellular connectivity obligations that persist for the life of the trial and are frequently underestimated.
  • The EDC component is newer than the eCOA heritage, so sponsors with complex data management requirements often keep an incumbent EDC and lose the single-database benefit that justifies the platform.
  • It is priced and scoped for sponsor-grade trials, which makes it a poor fit for investigator-initiated or academic studies that need outcome collection without the services layer.

Answered from the vendors’ own pages

Ambra Health: Is Ambra Health still sold under its own name?

Yes. Intelerad still markets Ambra Health as a named product line, but the standalone website redirects to Intelerad, and support and contracting run through Intelerad.

Signant Health: What is Signant best at?

Electronic clinical outcome assessment, particularly rated scales in central nervous system and psychiatry trials, together with rater training and endpoint quality services.

Ambra Health: Can Ambra replace our PACS?

For image exchange, archiving and clinical viewing, yes. For high volume diagnostic radiology reading it is generally deployed alongside a departmental PACS rather than instead of one.

Signant Health: Is pricing published?

No. Everything is quoted per study, and instrument licences, translations and devices sit on top of the platform cost.

Ambra Health: Is pricing published?

No. It is quoted by annual study volume, stored capacity and the scope of exchange connections.

Signant Health: Can I use it only for eCOA?

Yes. The modules are selected per protocol, and many sponsors take eCOA and eConsent while keeping an existing EDC.

Ambra Health: Does the viewer require software on referring physician machines?

No. The viewer is zero footprint HTML5, which is the main reason referring practices adopt it at all.

Signant Health: What drives the timeline?

Translation and linguistic validation of outcome instruments, which is per language per instrument and sits on the critical path to study start.
