Abstract

Our aim was to study the hemispheric asymmetry of the human brain through the simultaneous measurements of the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values within a homogeneous sample in regards to the gender, age and handedness. Method - Eleven young women were included in our diffu3 sion study performed on a 1.5 T MR scanner. We calculated the ADC and FA values in nine-nine region of interest points of the brain. The diffusion values were measured symmetrically in the right and left hemisphere of the brain and were then statistically compared to detect interhemispheric asymmetry. Results - We did not find any significant differences between the data of the two hemispheres in regards to the ADC values. However, we detected a significant right sided asymmetry in case of the globus pallidus in FA values (p=0.04). Conclusion - Our results of our study of young women suggest that diffusion asymmetry does not appear in case of ADC values and only slightly (in one ROI in our study) in FA values.
