Using Dynamic Contrast-Enhanced Magnetic Resonance Imaging Data to Constrain a Positron Emission Tomography Kinetic Model: Theory and Simulations

Figure 5

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