CSPAMM images of mid ventricular short axis slice and analysis model. A. Tags at the beginning of systole after ECG triggering. B. Same slice at end systole. C. Same slice at diastole with good persistence of tags. D and E show an example of CSPAMM images with the analysis model. D. In early systole, the epicardial border was manually drawn in green, endocardial border in red, superior right ventricular insertion site marked with a yellow triangle, and inferior insertion site marked with a blue triangle. The red donut is the analysis model with the myocardium partitioned in epi-myocardial, mid-myocardial, and endo-myocardial thirds shown in early systole in D and end-systole in E. Magenta dot is the center of the epicardial contour.
