Figure 1.

Typical set of cine images utilizing a steady-state free precession pulse sequence. From a 4-chamber long-axis view, serial short-axis cine images are acquired every 1 cm from base to apex of the heart. The left ventricular (LV) endocardial contours are planimetered in both end-diastole and end-systole and added to calculate LV end-diastolic volume (LV EDV) and LV end-systolic volume (LV ESV). The difference between LV EDV and LV ESV represents the LV stroke volume. LV ejection fraction can be calculated by dividing the LV stroke volume by the LV EDV and multiplying by 100. The same can be performed for the right ventricle (RV) to ascertain RV end-diastolic volume, RV end-systolic volume, RV stroke volume, and RV ejection fraction.
