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 un gated, 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 calciumburden.
  • Arterial Age: Contextualizes calcium burden againstpopulation data.
  • Lesion Count, Volume, and Mass: Detailed breakdown byindividual arteries (LM, LAD, LCX, RCA).3DVisualizations:Clear overlays for rapidinterpretation.

The Power of Personalized Quantitative Imaging

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

Clinical and Workflow Features

For Your Practice

Coronary Artery Calcification Analysis

CAC™ brings actionable cardiovascular risk data into theworkup of patients with breathlessness, expeditingdiagnosis and guiding referrals.For radiologists, itprovides objective, reproducible quantification, 3Dvisualization, and artery-specific scoring to ensurecomprehensive and efficient interpretation. The result is amore confident, timely distinction between cardiac andpulmonary causes of dyspnea, with higher diagnosticaccuracy 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.
