CAAS MR Solutions features segmentation of cardiovascular structures and enables the analysis of blood flow in the heart and large vessels based on multi-slice, multi-phase and velocity encoded MR images as well as measurement and reporting tools by providing the following functionality:
• Segmentation of cardiovascular structures and calculation of quantitative results
• Support signal intensity analysis for the myocardium
• Quantification of MR parametric maps (such as T1, T2, T2* relaxation)
• Visualization and quantification of blood flow velocity and directions
When the results provided by CAAS MR Solutions are used in a clinical setting to support diagnoses, the results are explicitly not to be regarded as the sole, irrefutable basis for clinical decision making.
Indications for use as stated in the FDA summary.
