Schematic overview of the SIR-IR method, where a selective 180º inversion RF pulse is performed before the standard (non-selective) 180º inversion RF pulse. Note that the inversion time is split into two delay parameters (TD1 & TD2). For the magnetization diagram, it is assumed that before image acquisition, blood present in the imaging slice at the time of the first (selective) 180º inversion RF pulse has been completely replaced by unaffected blood outside the imaging slice
