Echocardiographic quantification of myocardial function using tissue deformation imaging, a guide to image acquisition and analysis using tissue Doppler and speckle tracking

Additional file 1:

ROI tracking in tissue Doppler imaging. The ROI is tracked (bottom left) as described in the text in the basal segment of the RV. Note the changes in the strain-graph during the tracking. After careful tracking, the ROI follows the myocardial motion.

Impact of stationary artifact on 2DSE. Appropriate ROI in a 4-chamber view using 2DSE despite a prominent stationary artifact in the lateral wall. The ROI is color coded: yellow-red = negative SR, green = no SR and blue = positive SR. In the region of the artifact there is no reversal of SR values, all myocardial segments show identical color coding during each phase of the cardiac cycle. See figure 9 for additional information.

Deformation imaging of the right ventricle in a patient suspected for ARVD using 2DSE. 2DSE parameter extraction in the right ventricle. A ROI is tracked along the RV free wall and follows its movement during the cardiac cycle. An overlying color map is seen on the ROI: red indicates normal deformation; pink indicates reduced deformation and blue indicates no deformation, or stretch. See figure 16 for additional information.
