Schematic overview of the IR-T2 prep method, where T2 preparation is performed after the 180º inversion RF pulse. Note that the inversion time is split into two delay parameters (TD1 & TD2), separated by the T2 preparation module with duration TEeff. Due to the relatively long T2 relaxation times of scar and myocardium, their Mxy decreases quickly and thereby effectively ‘accelerates’ their Mz recovery during T2 preparation. As blood is hardly affected by T2 preparation, the Mz recovery of blood is effectively ‘paused’ during T2 preparation
