A. Example of superior manual segmentation performance. Machine learning-selected mask includes coronary sinus (arrow) that should not be included as part of LV myocardium. B. Example of superior performance of machine learning segmentation. Right atrium is incidentally included in manual segmentation of LV myocardium (arrows). However, machine learning segmentation clearly demarcates border of basal myocardium (arrowheads).
