Dynamic Contrast-Enhanced Imaging as a Prognostic Tool in Early Diagnosis of Prostate Cancer: Correlation with PSA and Clinical Stage

Figure 2

Comparison of tumor Ktrans, Kep, iAUC, and serum PSA level in patients with different clinical stages of prostate cancer. (a) Ktrans (0.11 ± 0.02 min−1 versus 0.16 ± 0.06 min−1; ), (b) Kep (0.38 ± 0.08 min−1 versus 0.60 ± 0.23 min−1; ), and (c) iAUC (14.33 ± 2.66 mmoL/L/min versus 17.40 ± 5.97 mmoL/L/min; ) were all lower in clinical stage T1c tumors than that in clinical stage T2 tumors; (d) there was no significant difference of serum PSA between clinical stage T1c and T2 patients (8.2 ± 4.5 ng/mL versus 9.8 ± 3.6 ng/mL; ).
