Abstract：Objective To explore the effects of different spatial resolutions on the quantitative parameters including relax-ation time T1,T2,and proton density(PD)obtained from synthetic magnetic resonance imaging(SyMRI).Methods This study included 30 healthy volunteers underwent brain MRI scans using SyMRI with three different spatial resolutions(voxel sizes of 2×2×2 mm,1×1×2 mm,and 1x1x4 mm,respectively).T1,T2,and PD values of the whole brain based on the quantitative maps were obtained from SyMRI,and the differences of various quantitative parameters with different spatial resolutions were compared using one-way analysis of variance.Results T2 and PD values showed significant statistical differences(P<0.05)at different through-plane resolutions,while,there was no statistical difference(P>0.05)at different in-plane resolutions.There was no statistically significant difference in T1 values at different spatial resolutions(p>0.05).Conclusion Different spatial resolutions have no effect on the quantitative parameter T1 of the brain.Different matrices have no effect on T2 and PD values,while,different slice thicknesses have a greater impact.
