Perfusion MRI derived parameter mappings of one rabbit with implanted VX2 tumor.

<p>A. Arterial input function for the simulation curve; and (B-E) ROIs selection for T_{RF Ablation}, T_residual, T_control and normal regions for claculation the K_trans, V_e, and K_ep parameters before RF Ablation treatment; F-J after RF Ablation treatment corresponding to A to E. All the mapping from A to J show reduced perfusion values in the RF Ablation treated tumor than that of the contralateral untreated tumors and before treatment in color coded mappings. K to L show the T2, T1 post contrast enhancement MRI before RF Ablation treatment and after treatment (M to N). All the mapping from K to N show instantly morphological chages of routine MRI in the RF Ablation treated tumor. The T2WI and T1WI showed the necrosic focus in tumor after RF Ablation (M, N).
