Fig. (2). Analysis of LV strain by cardiac magnetic resonance cine images. The LV endocardium (red) and epicardium (green) were outlined on the LV two-chamber long axis (a) and four-chamber long axis (b) images of end-diastolic. (c) The 3D volume tissue tracking model of LV automatically established (Source: Figure prepared by the author using the CVI42 post-processing software).

Fig. (4). Analysis of LA strain by cardiac magnetic resonance cine images. The LA endocardium (red) and epicardium (green) have been outlined on the LV two-chamber long axis (a) and four-chamber long axis (b) images of end-diastolic.
