This study aimed to assess the feasibility of respiration-triggered diffusion tensor imaging (DTI) of the normal kidney and to compare the results obtained with 3.0T and 1.5T imagers. FA and ADC values in cortex and medulla of the kidney were evaluated. DTI of the kidney at 3T showed better contrast between cortex and medulla and smaller standard deviation than those obtained at 1.5T in both FA and ADC values. The FA and ADC values were almost equal between DTIs obtained by 3T and 1.5T and agree with those values reported previously.
