: The six animals used in this manuscript submission were also used for a previous study for validation of the myocardial assignment technique. However, there is no overlap in the data presented in this submission with the previous study.In the previous report, reference standard and minimum cost path perfusion territories for the left and right coronary arteries were validated for the whole heart (both left and right ventricles). In the present study, these previously determined whole heart perfusion territories were cropped to a common left ventricle myocardial segmentation and compared with the AHA 17-segment model. Data regarding the coronary perfusion territories of the left ventricle coronary perfusion territories in the present study has not been published.
