[Abstract] Objective To explore the changes of brain volume and relaxation value in the early stage of early stage of Parkinson's disease (ESP) based on synthetic MRI (sMRI) technology and voxel-based morphometry (VBM) whole brain partitioning method, and provide imaging basis for the early diagnosis of this disease.Materials and Methods In this study, 22 patients with ESP were prospectively included in the ESP group, and 25 sex-and age-matched healthy control (HC) in the HC group. All subjects were scanned using GE 3.0 T MR to acquire conventional sequence, 3D T1WI and quantitative magnetic resonance imaging (MAGiC) scans, and performed Minimum Mental State Examination (MMSE) scoring. The MATLAB software SPM 12 data processing package was used to VBM whole brain partition of all data, and the gray matter volume (GMV), white matter volume (WMV) and brain region relaxation value of the whole brain and each brain region in different cortical and subcortical regions were obtained. The volume characteristics and brain region relaxation values between ESP group and HC group were compared, and the volume of brain regions, T1, T2 and proton density (PrD) values and MMSE scores were analyzed in the case group. The ROC curve was made for the brain region with the most obvious difference in correlation analysis results, and the relaxation values of each sequence were jointly diagnosed in this brain region.Results There were more cases in which the volume of brain regions correlated with clinical scales (P<0.05). There were differences in the relaxation values of some brain regions between the HC group and ESP, but the difference in the relaxation values of the right thalamus and the correlation with the MMSE score existed in all sequences, so the relaxation values of each sequence of the right thalamus were used for ROC diagnosis, and the relaxation values of the right thalamus in T1 and T2 sequences were used for joint diagnosis, and the AUC was 0.822 (0.697-0.911).Conclusions The results of this study showed that ESP patients had changes in right thalamic volume and brain region relaxation values. In this study, it is believed that the relaxation values of the right thalamus in the various sequences of sMRI can make an early diagnosis of PD.
