Characterization of ischemia‐induced inverse CEST Z‐spectral signal change. A, The R₁‐scaled inverse CEST Z‐spectral changes between the contralateral normal area (red) and ipsilateral ischemic region (blue). B, Intrinsic R_1ρ spectral changes between the contralateral normal area (red) and the ipsilateral ischemic region (blue). C, The R_ex spectral changes between the contralateral normal area (red) and the ipsilateral ischemic region (blue). D, The R_ex spectral difference between the contralateral normal area and ipsilateral ischemic lesion
