Circumferential and Longitudinal Strain are CMR measurement parameters used to evaluate progression of cardiac dysfunction. This example shows how to represent the findings of these tests in the CV domain.
Rows 1-3:
Show circumferential strain using the CMR Brand Type (CMRBRANDTYP) Feature tracking analysis for the left ventricular base, mid, and apex regions (CVLOC).
Row 4:
Shows the left ventricular global circumferential strain (CVLOC=LV Global) and (CVTEST=CIRCUMFERENTIAL STRAIN).
Row 5:
Shows the circumferential strain for the LV Basal Inferoseptal segment (CVLOC= LEFT VENTRICULAR BASAL INFEROSEPTAL SEGMENT).
Rows 6-8:
Show the longitudinal strain for 4 chamber, 3 chamber, and 2 chamber of the left ventricle.
Row 9:
Shows the left ventricular global longitudinal strain (CVLOC=LV Global) and (CVTEST=LONGITUDINAL STRAIN).
Row 10:
Shows longitudinal strain for the left ventricular, 4 chamber, basal inferoseptal segment.
