The Principal of Dynamic Contrast Enhanced MRI, the Method of Pharmacokinetic Analysis, and Its Application in the Head and Neck Region
Figure 1
Schematic illustration of the TK model. The model assumes equilibrium of the contrast media between the plasma and the extravascular-extracellular space (EES) and the isodirectional permeability and : influx forward volume transfer constant (into EES from plasma), : fractional volume of EES per unit volume of tissue, : the efflux rate constant from the EES to plasma .
