Catenary compartment model of contrast agent exchange in expanded myocardium EES, with pericapillary and remote components. The pericapillary component has fractional volume fc; the remote component has fractional volume (1-fc). The pericapillary compartment exchanges with both the plasma space and the remote compartment; the remote compartment only exchanges with the pericapillary compartment, at a rate dependent on the effective exchange time constant, tcr
