A Comparative Study of Two-Compartment Exchange Models for Dynamic Contrast-Enhanced MRI in Characterizing Uterine Cervical Carcinoma

Figure 1

Example of a patient with stage IIb cervix cancer. (a) ROIs for cervix carcinoma (blue) and normal cervix tissue (red) are shown for the central four slices of the DCE-MRI dataset, and the location within the iliac artery where the AIF was sampled was marked with a red dot. (b) Sampled AIF used in model fitting. (c) Parameter maps generated using the three models (AATH, SC, and DP) for tumor and the normal tissue ROIs. (d) Examples of curve fittings for a tumor voxel. In the legend, the four numbers within square brackets beside each model are their respective parameter values: (F_p (mL/min/100 mL), V_p (mL/100 mL), PS (mL/min/100 mL), V_e (mL/100 mL)).
