A comparison between the calculated values using an exponential model and the experimental values obtained with the volumetric postenhancement computed tomography scan. The error is the difference between the predicted and the experimental concentration. s.d. is the standard deviation from the average. The prime symbol is used when a patient has two metastasis in the studied FOV.

^aAverage error value obtained when the absolute values of the errors are taken.
