Circumferential and Longitudinal Strain are CMR measurement parameters used to evaluate progression of cardiac dysfunction.
Example
This example shows the representation of circumferential and longitudinal strain findings in the CV domain. The sponsor used the "CMRBRANDTYP Feature Tracking" analysis method (CVANMETH).
Rows 1-3:
Show circumferential strain for the left ventricle base, mid, and apex regions.
Row 4:
Shows circumferential strain for the LEFT VENTRICULAR BASAL INFEROSEPTAL SEGMENT.
Row 5:
Shows global circumferential strain.
Rows 6-8:
Show longitudinal strain for 4 chamber, 3 chamber, and 2 chamber views.
Row 9:
Shows longitudinal strain for the LEFT VENTRICULAR BASAL INFEROSEPTAL SEGMENT.
Row 10:
Shows global longitudinal strain.
