Circle Cardiovascular Imaging vs CureMetrix
Circle suits a cardiology group reading coronary CT. CureMetrix suits a breast imaging network with screening volume. Both hold clearances under product code QIH.
CureMetrix's cmAngio detects and quantifies breast arterial calcification on screening mammograms. Its openFDA record runs from V1.0 (K232367, October 5, 2023) through V1.6 (K250754, April 10, 2025) to V2.0 (K260980, July 30, 2026). The vendor says it is live in over 400 US sites, citing internal data, and gives an AUC of 0.98 to 0.992 across DBT and FFDM cases. Both figures are the vendor's own.
Circle holds twelve openFDA 510(k) records between November 2008 and October 2025, filed under Circle Cardiovascular Imaging and a second applicant name, Circle Neurovascular Imaging. A health system running a mammography program and a coronary CT service would be reading different studies with each tool. Circle's website and CureMetrix's homepage show no price.
