Figure 1From: Magnetic resonance imaging detects significant sex differences in human myocardial strain MRI Motion Tracking. Tagged MRI images of the left ventricle are shown at end-diastole, mid-systole, and end-systole. Images are acquired approximately every 30 ms throughout the complete heart cycle. Tag lines are semi-automatically tracked through systole, and displacements are computed using a previously described and validated method [20].Back to article page
