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

Figure 2

A 69-year-old man with prostate cancer Gleason 3 + 4. (a) T2-weighted image shows a hypointense focal​ ​ area on left midgland in the peripheral zone. (b) DWI with -value of 1000 s/mm² shows a slight focal increased signal in the left peripheral zone almost indistinguishable compared to surrounding benign tissue. (c) DWI -value of 2000 s/mm²; the tumor is easily identifiable compared to the 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 intensity on the left midgland in the peripheral zone.
