Figure 8:

Cardiac strain values across volunteers (N=30) calculated after combining cDTI and DENSE. (A) Computed Myofiber strain (E_{ff_C}) and (B) circumferential strain (E_{cc_C}) at endo, mid, epi layers, and across the left ventricular (LV) wall. The black dashed and dotted lines represent the median and the first and third quartiles across volunteers; the red dashed line provides a −0.15 strain reference; the colored solid lines are individual medians per volunteers. (C) Transmural distribution of E_{ff_C}, E_{cc_C}, and of the absolute difference of E_{ff_C} and E_{cc_C} at peak-systole. Blue solid lines represent the transmural median per volunteer and the box plots represent the median and IQR across volunteers. Statistical differences between E_{ff_C} and E_{cc_C} have been assessed using a pair-wise Wilcoxon sign rank test: p-values<0.01 are represented by (**) and p-values<0.05 by (*).
