CAC™

Non-Contrast Cardiothoracic Risk Assessment with AI-Powered Detection

CAC™ utilizes advanced artificial intelligence to identify and quantify coronary artery calcification from non-contrast chest CT imaging—including both new and existing gated or ungated, standard or low-dose scans. As part of 4DMedical’s cardiopulmonary diagnostic suite, CAC streamlines comprehensive evaluation of patients with unexplained shortness of breath (dyspnea), helping clinicians determine whether symptoms are caused by cardiac, pulmonary, or multifactorial disease.

FDA 510(k) Cleared, CE Mark Certified,ARTG approval pending

Robust, Automated Cardiac Risk Quantification

CAC gives clinicians a clear cardiac risk profile with:
  •  Agatston Score (AS): Gold standard for coronary calcium burden.
  • Arterial Age: Contextualizes calcium burden against population data.
  • Lesion Count, Volume, and Mass: Detailed breakdown by individual arteries (LM, LAD, LCX, RCA).
  • 3D Visualizations: Clear overlays for rapid interpretation.

Actionable Insights

Reports summarize these findings in a structured, easy-to-read format, including risk stratification percentiles—helping guide lifestyle and preventative care discussions. All results are generated directly from a routine chest CT, such as those done for lung cancer screening, without the need for additional imaging.

Clinical and Workflow Features

For Your Practice

Coronary Artery Calcification Analysis

CAC™ brings actionable cardiovascular risk data into the workup of patients with breathlessness, expediting diagnosis and guiding referrals.For radiologists, it provides objective, reproducible quantification, 3D visualization, and artery-specific scoring to ensure comprehensive and efficient interpretation. The result is amore confident, timely distinction between cardiac and pulmonary causes of dyspnea, with higher diagnostic accuracy and better outcomes for patients.

Suggested use cases for CAC

    •  
    • 1 Scan—more actionable information: Calcification analysis from the same scan used in lung cancer screening programs
    • Earlier targeted care: Triage unexplained dyspnea determine/rule-out source of symptoms
    • Population Health Screening: Incidental CAC detection on all eligible chest CTs across health systems

    With CAC, you have a powerful, FDA-cleared tool for fullyautomated detection, visualization,and quantification ofcoronary artery disease—enabling faster, more thorough carefrom a single scan.
