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

Figure 1

A 71-year-old man with prostate cancer Gleason 4 + 3. (a) T2-weighted image on the axial plane shows a hypointense focal​ ​ area on left apex in the transitional zone. (b) DWI -value 1000 s/mm² shows a slight increased signal in the left transitional zone. (c) DWI -value 2000 s/mm²; signal-to-noise ratio is decreased but signal intensity between the tumor and benign tissue is more evident. ((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 apex in the transitional zone.
