HealthCCSng

Nano-X AI Ltd.

Non-invasive post-processing of routine non-gated, non-contrast CT studies containing the entire heart in adults aged 30 to 85 to evaluate coronary calcified plaque and estimate coronary calcium score and category.

Evidence status: each field states its source quality, applicability, and review date. Research pending, information not established, and vendor documentation pending remain distinct outcomes.

What this tool is for

Start with the authorized purpose, then verify how it fits your service line and reading workflow.

Exact purpose
Non-invasive post-processing of routine non-gated, non-contrast CT studies containing the entire heart in adults aged 30 to 85 to evaluate coronary calcified plaque and estimate coronary calcium score and category.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Intended users
Radiologists and other interpreting clinicians, with further assessment available to cardiologists, general practitioners, or other clinicians.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Care setting and population
Inpatient or outpatient CT workflow, including opportunistic use such as lung cancer screening, for adults aged 30 to 85.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Workflow role
Parallel post-processing and coronary-calcium quantification in the standard workflow; results are for clinician review, and final diagnosis and clinical decisions remain independent clinician responsibilities.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Required input
Routine non-gated, non-contrast CT studies containing the entire heart in adults aged 30 to 85; DICOM input. The validation data included CT slice thicknesses from 0.5 to 5 mm and four CT manufacturers.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Output and human action
An estimated coronary calcium score, an estimated category of Zero (0), Low (1-99), Medium (100-399), or High (>=400), representative axial images with calcified areas annotated for non-zero results, and status or error outputs for non-compliant, no-category, or failed studies.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Limitations
Results are informational and not intended as a stand-alone basis for risk attribution or clinical decision-making. The clinician must review the CT independently; the packet notes that calcium scoring on non-gated CT is less accurate than on gated CT. Input validation can produce non-compliant, no-category, or failure outcomes.

Regulatory identity

FDA record and catalog context

The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.

Implementation

Questions for IT, informatics, and operations

Use these fields to structure a vendor demo, security review, and implementation estimate.

Integration
Receives DICOM studies from a storage or hosting application such as the Nanox Imaging Analytics Platform or another platform, validates the input, and returns successful analysis results to the hosting application; the packet does not establish every local interface or deployment model.

Deployment and data flow
On-premise
  • Public source
  • Exact FDA submission
  • Checked 2026-08-13

Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.

Security and privacy
Vendor documentation pending
  • Vendor confirmation
  • Exact FDA submission
  • Checked 2026-09-08

Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.

Training and support
Vendor documentation pending
  • Vendor confirmation
  • Exact FDA submission
  • Checked 2026-09-08

Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.

Monitoring and change control
Vendor documentation pending
  • Vendor confirmation
  • Exact FDA submission
  • Checked 2026-09-08

Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.

Input or output interoperability

DICOM is explicitly referenced in the described input, output, or workflow.

Evidence

Performance evidence

Metrics are shown only when they are tied to a source, endpoint, population, and tested product version. Candidate literature without exact product and version linkage is not shown as product evidence.

Evidence summary
FDA retrospective simulated-use standalone testing used a validation dataset of 436 cases from four healthcare institutions, with algorithm results returned for 427 cases (97.94% yield). Ground truth coronary-calcium category was the majority agreement of two of three U.S. board-certified radiologists. Overall categorical agreement was 89.46% (95% CI 86.15%-92.21%), with category agreements of 86.63% Zero, 87.65% Low, 87.36% Medium, and 98.85% High. The estimated score correlated with ground truth at Pearson r=0.959 (95% CI 0.9499-0.9655, p<0.0001).

Safety and lifecycle

Postmarket record

Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.

Postmarket safety review
The exact-identifier FDA recall query returned no native recall record for K241440. This limited result does not establish absence of recalls or other safety information and does not cover later versions, family records, MAUDE reports, corrections, or field notices.

Exact-submission ACR model-card fields were normalized under the current provenance rules; vendor and independent-study confirmation remain distinct. Exact FDA scope controls clinical claims. ACR provides bounded exact-submission catalog context. Candidate literature metadata remains a discovery queue until full-text identity, endpoint, population, and version review is completed. Automated exact-name discovery found 0 PubMed and 0 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.

Candidate leads remain unpublished until a human confirms the exact product and tested version.
