Figure 5.

Example of biventricular volume analysis with exercise CMR. The images presented in this figure are end-diastolic image slices in the short axis that cover the heart from apex (upper left image) to base (lower right image). At all slice levels, LV and RV endocardial borders are delineated in red and pink, respectively. The LV and RV volume within each slice is derived as the area within the red and pink contours, respectively, times slice thickness. For each ventricle, the total end-diastolic volume is calculated as the sum of the volumes of all slices from apex to base. Similarly, LV and RV end-systolic volume is the sum of the slice volumes obtained at end-systole (not shown here).
