Purpose: To study age dependencies of ADC histogram and impact of brain abnormalities on ADC in a large and wide age ranged population. Methods: Brain data of 667 subjects (2 days-93.8 years) were obtained by DW-SE-sshEPI and ADC histograms of the whole brain were generated. The subjects were divided into normal and abnormal groups by MR findings and clinical histories. Results: The abnormal group showed higher ADC peak values compared with the normal. Conclusion: The aging patterns of ADC peak values of normal and abnormal brain groups have been demonstrated in a large and wide age ranged population.
