Comparison of Three Two-Compartment Models

Note.-K^trans in Tofts and Kermode model, meaning contrast flux between intravascular and extravascular extracellular space. V_e = fractional volume of extravascular extracellular (interstitial) space, V_p = fractional volume of intravascular space, K_ep = K^trans/V_e, in Larsson model, and K_ep K₂₁ = K_ep in Brix model, meaning contrast flux from extravascular extracellular space to intravascular space, K_el = contrast elimination rate from plasma, A^H = fractional volume of interstitial space in Brix model
