Radial Strain Contour Plots in Men and Women. This left ventricular color contour plot graphically demonstrates the differences in radial strain between men and women. Average strain values for both groups were computed for a grid of 15,300 points within the ventricle. The differences between the male and female average values at corresponding points were used to generate the contour plot in this figure. All shades of blue in the plot indicate regions where radial strain values were larger in women, while yellow and red colors indicate regions where radial strain values in men exceeded those in women. There is no statistically significant difference in radial strain between men and women when compared on a regional or global left ventricular basis.
