Characteristics of the Diffusion-Weighted MR Imaging in NormalHuman Brain in Various Age Groups

Sun Jing Yu BolangImage Center,First Hospital,Xi′an Jiaotong University,Shaanxi 710061  
Purpose:To study the characteristics of diffusion-weighted imaging (DWI) and apparent diffusion coefficint (ADC) in normal human brain in various age groups.Materials and Methods:Fifty younger volunteers and fifty older volunteers with normal MR imaging and diffusion-weighted MR imaging were selected.For each one,ADC were calculated on diffusion-weighted MR imaging and compared between various regions and various age groups.Results:The ADC average values of white matter,thalamus,lentiform nucleus and caudate nucleus in older volunteers were 0.765×10~(-3)mm~2/s?0.790×10~(-3)mm~2/s?0.769×10~(-3)mm~2/s?0.781×10~(-3)mm~2/s respectively.The ADC average values of white matter,thalamus,lentiform nucleus and caudate nucleus in younger volunteers were 0.743×10~(-3)mm~2/s?0.759×10~(-3)mm~2/s?0.741×10~(-3)mm~2/s,0.762×10~(-3)mm~2/s respectively.Differences of the ADC average values were observed between the two groups.The ADC average values of ventricles in older and younger volunteers were 3.338×10~(-3)mm~2/s and 3.239×10~(-3)mm~2/s respectively.No difference of the ADC average values was observed.Conclusion:The normal ADC values in various age groups measured quantitatively provides the changes between the two groups and basic reference for differential diagnosis.
