Modeling ¹⁸F-FDG Kinetics during Acute Lung Injury: Experimental Data and Estimation Errors

Figure 8

Estimation Errors as a Function of k₅.

(A) Relative errors of k₁ (ε_k1 = (k_1S-k_1F)/k_1F ·100), k₂ (ε_k2 = (k_2S-k_2F)/k_2F ·100), k₃ (ε_k3S = (k_3S-k_3F)/k_3F·100) and F_e (ε_Fe = (F_e-F_ei)/F_ei·100) versus k₅ at a k₅/k₆ ratio of 0.14, 0.69 and of 1.24; (B) absolute errors of k₁ (Δ_k1 = k_1S-k_1F), k₂ (Δ_k2 = k_2S-k_2F), k₃ (Δ_k3S = k_3S-k_3F) and F_e (Δ_Fe = F_e-F_ei) versus k₅ at a k₅/k₆ ratio of 0.14, 0.69 and of 1.24.
