This example shows the representation of circumferential and longitudinal strain findings in the CV domain.
Check with team and CT - these are different than the 17 segments in the other example. Not sure if these can be generalized to the heart or if the locations need to be specific by ventricle (seems like but I am not sure). It may indicate the view of 4 chambers from the left ventricular wall side (left ventricle, 4 -chamber)
Rows 1-3:
Show circumferential strain using the "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.
