Function is also possible with CT using the exact same post processing method? Because of the streamlined analysis workflow, Medis Suite allows you to compare CT and MR function studies with the highest diagnostic confidence.
Contours traced during the LV function analysis can be loaded into the QStrain app for subsequent strain analysis based on features tracking MR
