Figure 4

ARFI images of anatomic structures in specimen A after DDG. (a) axial section, (b) sagittal section, (c)-(e) coronal sections at different axial depths (5.8, 11.6, and 16.1 mm, respectively). The dashed white lines indicate the intersections of the orthogonal planes in the images. The zonal structures are well correlated with those in the diagrams of prostate anatomy (Figure 1), and denoted with PZ, CZ and TZ. In the coronal sections, the prostate images are oriented with the basal area on the top and apex region at the bottom. The CZ is located in the base and appear stiffer than other anatomical structures. The verumontanum (purple arrow) is located in the middle of the prostate and shown softer than the surrounding tissue.
