Echoes selected for calculating R2’ using each standard approach, with idealized mono-exponential T2 and SE decay curves in dashed lines. a) ASE uses a single echo from four modified GESFIDE sequences; b) the standard GESFIDE approach uses the FID and refocusing echoes from a modified GESFIDE sequence; c) the GESSE approach uses the refocusing and post-SE dephasing echoes from a modified GESFIDE sequence; d) the combined approach uses the FID echoes from a modified GESFIDE sequence and the echoes from a CubeQuant sequence.
