Dedicated tools for assessment of coronary artery disease

Reading and reporting of cardiac CT studies with server-side processing and AI-enabled segmentation.

cvi42 | Plaque

cvi42 | Plaque empowers cardiac imaging teams with AI-enabled, on-premise quantification of atherosclerotic burden. It delivers precise measurements of plaque volume, burden, composition, and distribution, all fully integrated into your CT workflow.

  • AI-automated coronary lumen and wall segmentation
  • Detailed assessment of calcified, non-calcified, and low-attenuation plaques
  • Per-lesion and per-vessel plaque analysis
  • Remodeling index assessment helps identify high-risk plaques beyond stenosis severity
  • Enhanced coronary reporting

cvi42 | CORE CT Coronaries

Open a study with completed AI segmentation of the coronary artery.

  • Zero-click primary and secondary coronary artery centerline segmentation
  • 2-click stenosis assessment
  • MPR and CMPR visualizations
  • Automatic 3D heart view generation for editing and quality assessment
  • Lesion-level total occlusion marking
  • Single- and dual-reference marker for stenosis calculation

cvi42 | CORE CT Calcium

Open a calcium scoring study with AI segmentation already completed.

  • Zero-click AI powered calcium definition
  • Simple editing with cluster propagation
  • Percentile risk display based on the MESA study*

cvi42 | CORE CT Function

Open a study with AI segmentation for Cardiac CT heart function already completed.

  • Server-side pre-processing and 3D-based, AI-driven left and right heart ventricles segmentations.
  • User-friendly tools for manual editing, such as AutoFOV viewport alignment.
  • Endoluminal view and overlay hiding capabilities, enabling a clearer understanding of underlying anatomy.

cvi42 | Strain

CT Strain is for research use only.


Unlock deeper clinical insights with our new strain AI designed and trained for Cardiac CT studies. By pre-processing multi-phase volumetric CT studies and leveraging data-driven analyses, cvi42 now allows you to compare subtle changes over time and detect early signs of dysfunction.

  • Comprehensive view of myocardial tissue deformation, regional dysfunction and the heart’s mechanical properties, all without additional scans.
  • AI-based re-slicing of multi-phase volumetric CT studies to create short-axis and long-axis series for strain assessment.
  • AI-based contouring of reformatted series.
  • Automated calculation of radial, circumferential and longitudinal peak strain, strain rate, displacement, velocity, torsion and torsion rate.
  • Easy to deploy and integrate smoothly into your existing clinical environment
