Circle Cardiovascular Imaging vs Qure.ai
Qure's qER (K200921, 2020) and qER-CTA (K251610, 2025) are triage records under code QAS, aimed at emergency radiology groups reading head CT. Qure also lists qXR-PTX-PE triage for pneumothorax and effusion on chest X-ray and qCT LN Quant for nodule volumetry.
A stroke service scoring ASPECTS on acute stroke CT has Circle's StrokeSENS ASPECTS (K250221, 2025), studied in a 2026 AJNR multi-reader multi-case paper. Qure's ten openFDA records include qER-CTA and no ASPECTS product, so that service goes to Circle.
A national TB program is a different Qure buyer. Qure says WHO endorsed its chest X-ray solution for TB screening without a human reader in 2021, and none of Qure's ten openFDA records is named for TB screening. An independent evaluation of 12 AI solutions (Scientific Reports, 2021) put qXR v3 at 95.5% sensitivity and 48.7% specificity at one threshold.
