Post-contrast T1-mapping enables prescription of a numeric TI for optimal myocardial nulling on LGE imaging directly on the CMR scanner console - illustration in a patient with prior myocardial infarction. (A) Post-contrast T1-map, directly reconstructed on the CMR console, with a region of interest (ROI) placed in remote myocardium using standard tools in the console image viewer. The ROI provides a mean T1 value from which to calculate the inversion time: TI = 0.69 × post-contrast T1. (B) LGE image with correctly nulled myocardium acquired using TI calculated from post-contrast T1-mapping.
