Figure 5: The concordance correlation coefficient between the estimated and true values for the time courses as a function of error in the DCEMRI parameters for a single set of PET kinetic parameters. The method is able to return the time courses faithfully when the DCEMRI parameter error is less than 5%. With higher error in the DCEMRI parameters, the CCC remains above 0.95 on average, though some realizations returned CCC values as low as 0.9.
