Premarket evidence — what FDA accepted

Device typesamd
source quote (p.4)
“The iCAC Device (or the “subject device”) is a standalone software as a medical device (SaMD) that provides adjunctive information to a radiologist for an estimate assessment of the presence and quantity of coronary artery calcium (CAC) from routine, non-contrast, non-gated chest computed tomography (CT) scans.”
Algorithmdeep-learning-based computer vision algorithm
source quote (p.4)
“The device uses a deep-learning-based computer vision algorithm for its assessment.”

source quote (p.10)
“The iCAC device demonstrated an overall alignment rate of 79.7% and calcium-score-group level positive predictive values of 68.1% to 90.1%, thus satisfying both the primary acceptance criteria for the pivotal testing study.”

Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device); a recall is shown as device-attributed only when the recall record itself lists this clearance number. Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.

Reimbursement — how devices like this got paid

Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).

Applicable FDA guidance — what the submission is measured against

FDA guidance documents and guiding principles applicable to 510(k) AI/ML devices in the Radiology panel. A curated reference index, not legal or regulatory advice — each item states its own status, and a draft is never binding.

Applicability is derived from the device's FDA advisory panel and pathway — cross-cutting guidances apply to every AI/ML device; panel-specific ones are flagged. Titles, dates, and links verified against fda.gov as of July 2026.
