Abstract

Objective: To investigate the normal apparent diffusion coefficient(ADC) values of the abdominal organs of the preschool healthy children on a 1.5T MR. Methods: Sixty healthy preschool children were examined with DWI using b values including 500 s/mm2, 700 s/mm2 and 1 000 s/mm2. The ADCs were calculated with ROIs positioned in the parenchyma of the liver, kidney, spleen and pancreas. The ADCs were compared statistically using analysis of variance(ANOVA), P<0.05, was considered as significant. Results: There was a statistically significant difference in ADC values among the same parenchyma organs at different b values. There was a statistically significant difference in ADC values among the four solid organs at same b values. Conclusions: The ADCs of parenchyma organs in the abdomen of preschool healthy children were kidney>pancreas>liver>spleen. This study provide valuable refence for the diagnosis of parenchyma organ disease by using DWI.
