Evaluation of the developed methodology in a second NHP. A. The FAPOST map was normalized with the corresponding FAPRE map to produce the ΔFA map that revealed a BBB opening volume about 75.14 mm3 similar to the 81.29 mm3 volume obtained from the RGd-T1w quantification. B. Polar and azimuthal angle distributions in the ipsilateral and contralateral hemispheres within the ROI are presented showing a decrease by 32.18% and 31.18% of the v1POST-IPSI polar angle range compared to the v1PRE-IPSI and v1POST-CONTRA, respectively. Along the same lines, the azimuthal angle range of the v1POST-IPSI decreased by 5% and 7.95% compared to v1PRE-IPSI and to v1POST-CONTRA respectively. C. The S0 image along with the L1 and MD maps are presented for image quality assurance.
