Abstract

Objective To compare ADC value of DWI and DTI in normal adult brain.Methods The routine MRI were performed in 27 healthy volunteers,in which 15 volunteers were performed with DWI or DTI with 6,15,25 diffusion gradient directions.Then analysed images of DWI and DTI with Dtistudio 2.4.ADC value of DWI,eigenvalues(λl,λ2,λ3) and Trace,ADC value of DTI are measured or calculated at 10 ROIs of all volvnteers image in DtiStudio 2.4 software.Statistical analysis was performed.Results ADC value is not affected by diffusion gradient directions(p0.05).Conclusion There is no significance differences of ADC value of normal adult brain between DWI and DTI.
