The purpose of this study was to evaluate the value of diffusion spectrum imaging (DSI) MAP diffusion model in the changes of brain tissue microstructure in patients with primary essential hypertension, as well as the differences of various parameters including RTOP, RTAP, RTPP, QIV and MSD between the hypertensive group and the normal control group. The results showed that there were significant differences between RTOP and QIV. All the MAP-MRI parameters showed obvious differences in detecting the changes of brain structure microstructure in the early stage of hypertension, especially the RTOP and QIV parameters.
