1st choice for Cardiovascular Imaging Software Solutions

LV & RV Function powered by qmass mr iconQMass


  • Highly reliable and robust quantitative analysis – the nr.1 vendor-independent choice of many departments for more than 15 years. The QMass ventricular function module has supported clinical research in over 650+ peer reviewed publications
  • The user interface makes function analysis easy and practical
  • New: Novel deep learning algorithm for fully automatic LV contours
  • Other algorithms include such as LiveContour for quick semi automatic LV contours and MassK allow for quick exclusion of papillary muscle and trabeculations

Features included:

  • Global Function
  • Left ventricle (LV) and right ventricle (RV) volume analysis
  • NEW: fully automatic LV contour detection based on a novel deep learning algorithm, for more information see this article
  • Guided workflow for left and right ventricle volume analysis
  • Absolute and indexed results
  • Choose from different normal ranges
  • Add z-scores to results
  • Biplane Analysis
  • Enhanced LV endocardial “LiveContour” detection
  • “MassK” algorithm available for automatic segmentation of papillary muscles and trabeculations
  • Regional Function Analysis
  • Wall motion analysis
  • Wall thickness and wall thickening measurements
  • Wall thickness changes over time
  • Results are displayed within curves or bulls eye
  • Display of results in AHA 16 segment model
  • Other features include
  • Visual scoring for wall motion, perfusion and infarct size

Did you know that:

  • 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
