Example of the different measurement approaches. Colour encoded T1 maps in short axis (SAX) orientation with examples of different measurement approaches. (a-c) Global approach with the region-of-interest (ROI) including the whole apical (a), midventricular (b), and basal (c) SAX slice (in the latter case at the transition from midventricular to basal). (d) mid short axis (mSAX) approach with ROI placement within the midventricular short axis slice. (e) midventricular septal wall (ConSept) approach with ROI placement conservatively within the midventricular septum, taking care to avoid “contamination” with signal from the blood pool
