The purpose of our study is to establish reproducibility of ADC measurements in normal and diminished function native and transplant kidneys at 1.5T and 3T. ADC value variability was low in all four groups at 1.5T and 3T, with all mean coefficient of variation measurements at or below 5% per group. While challenges such as bulk motion and susceptibility artifact must still be overcome, particularly at 3T, our data indicate that DWI is reproducible at both 1.5T and 3T over a range of eGFR in both native and transplant kidneys.
