Standard deviation (SD) values were computed from the parameter values estimated by the three readers and then were averaged across all kidneys. The coefficient of variation (CV) for a parameter is the ratio of the SD over the mean value between the three readers. WK refers to the whole-kidney model, CM to the corticomedullary model.
