DWI of Prostate Cancer: Optimal 𝑏-Value in Clinical Practice

Figure 3

A 74-year-old man with prostate cancer Gleason 4 + 4. (a) T2-weighted image shows a hypointense focal​ ​ area on right midgland in the peripheral zone. ((b) and (c)) DWI -value of 1000 s/mm² and -value of 2000 s/mm² show a focal increased signal in the right peripheral zone easily distinguishable from the surrounding benign tissue. ((d) and (e)) ADC maps obtained with -values of 0–1000 s/mm² (d) and 0–2000 s/mm² (e) show the tumor as a focal area of decreased signal on the right midgland of the peripheral zone.
