A diagram to measure T1 values on the myocardium. Each region-of-interest (ROI) was drawn on the middle third of the free walls of both ventricles (right ventricle (RV) outlined in red and left ventricle (LV) outlined in blue) and septum (orange line) based on the inner junctional points (red asterisks) in reference to the exact middle of the LV on the short axis plane. Additionally, circular ROIs were drawn at the anterior (green circle) and inferior (purple circle) septal insertion points (SIPs)
