Reporting standards questions
Which radiology reporting standards does RadVector apply?
RadVector applies 9 radiology standards with one deterministic engine: Lung-RADS, BI-RADS, TI-RADS, LI-RADS, O-RADS, PI-RADS, Bosniak, Fleischner, DEXA. Validated criteria packs, which may produce output marked usable: BI-RADS, Fleischner, DEXA. Draft packs under validation, which answer as advisory: Lung-RADS, TI-RADS, LI-RADS, O-RADS, PI-RADS, Bosniak.
What is the difference between a validated and a draft criteria pack?
A validated pack has been audited against the published standard and names its validator and validation date on every verdict; only a validated pack with a confident decision may be marked usable for output. A draft pack applies the same rules but answers as advisory and is marked not usable for output until validation is complete.
Is there one API for Lung-RADS, BI-RADS, TI-RADS, LI-RADS, O-RADS, PI-RADS, Bosniak, Fleischner and DEXA?
Yes. RadVector API evaluates findings against every applicable standard in one call to POST /v1/inference/evaluate and returns each verdict with its criteria pack, version, validation status and a trace id. GET /v1/guidelines lists every pack with its edition and status.
RadVector is clinical decision support for qualified professionals, not a diagnostic device; the radiologist makes the final determination.
