CT Reading Support
(incl. Coronary Artery Segmentation & Calcium Scoring)
cvi42 is intended to be used for viewing, post-processing, qualitative and quantitative evaluation of cardiovascular CT in DICOM format. cvi42 for CT images, provides quantitative measurements for the assessment of coronary artery disease, including coronary artery centerline segmentation, stenosis assessment, and MPR/CMPR visualizations, clinicians can swiftly navigate through studies. The solution also streamlines calcium scoring studies with AI segmentation.1
Plaque Assessment
cvi42 is a software application that supports clinical diagnostics of cardiac CT images including quantitative measurements of calcified plaques in the coronary arteries (calcium scoring), specifically Agatston and volume and mass calcium scores, evaluation of heart structures including coronaries, aortic and mitral valves.1

Limitations
- The Strain Module implements an algorithm for modeling deformation from a two-dimensional (2D) version of the nearly incompressible deformable model and provides reasonably accurate estimates of the global strain measures. However, similar to other devices with such application it poses the following limitations:
- The accuracy of the estimates is limited by the image acquisition, image quality, pixel resolution, temporal resolution, presence of artifacts and noise.
- Results are dependent on the contours; the accuracy can be improved by providing contours in more phases.
- There is no established gold standard currently available across vendors and modalities; variability in results may exist comparing with different vendors or modalities.
- Plaque assessment results may differ between whole vessel or stenosis area selection. It is recommended to select smaller region that avoids intersections or bifurcations.
- Plaque may be incorrectly identified in the center of the vessel. Sculp tool can be used to restore the lumen in the region.
- Removing control points from the centerline can lead to varying results.
