MR Reading Support
cvi42 provides strain analysis of MR images by providing measurements of 2D LV myocardial function along with measurements of 2D RV and 3D myocardial function. The software allows for tissue characterization of cardiac MR Images and perfusion analysis of cardiac Images and includes flow quantifications based on velocity encoded cardiac 2D images. It supports clinical diagnostics by quantitative measurement of the heart and adjacent vessels and by using area and volume measurements for measuring LV function and derived parameters.4
4D Flow
cvi42 allows simultaneous acquisition of 3D morphology and time-resolved blood flow velocities in three spatial directions. This module enables a variety of options for visualizations of complex blood flow patterns. It also facilitates the retrospective quantification of flow parameters with its flexible plane placement function.4

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.
