We have demonstrated the precision of pharmacokinetic parameters and its effect due to duration of the time-intensity signal. Our results demonstrate that for the prostate case it is preferable to have scan duration of 5 minutes. Scan durations of more than 6 minutes do not generally contribute to any further improvement in the parameters.
