Fig. 1C —66-year-old man with local tumor progression of prostate
cancer in left lobe (prostate-specific antigen level, 2.38 ng/mL; Gleason sum
score, 8). Parametric images of wash-in rate (C), maximal enhancement
(D), and time-to-peak (E) show color-coded area (arrow)
corresponding to site in A and representing possibility of local tumor
progression. In this case, T2-weighted MRI with diffusion-weighted imaging was
equivalent to dynamic contrast-enhanced parametric imaging.
