Robust estimation of hemo-dynamic parameters in traditional DCE-MRI models
Fig 2
Bias and standard deviation plots of entire digital phantoms for the Tofts and 2XC model parameters as a function of SNR.
In panels A and B, the bias and standard deviation for the ETM model parameters are displayed as a function of SNR, while the similar plots for the 2XC model parameters are presented in panels C and D. The Bayes and LM parameters are displayed in blue and red, respectively and the insert in A and C define the symbols used for the model parameters.
