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

Figure 6

The error in the estimated PET kinetic parameters as a function of the error in the DCE-MRI parameters. Each panel corresponds to a different set of PET kinetic parameters. For each parameter combination, the error in the PET parameters is below 25% provided the error in the DCE-MRI parameters is below 10%. As the DCE-MRI parameter error increases, the error in the PET parameters exceeds 40% in some cases (see panel (d)).
