Figure 3a:
Images in a 63-year man with PCa (stage pT4apN1, Gleason score 4+5 = 9). (a) Axial DW (b value, 1000 sec/mm2) MR image shows hyperintense, round, noncontinuous structure (arrow) corresponding to round irregular LN in external iliac region on the right on (b) coronal three-dimensional T2-weighted image (sampling perfection with application optimized contrasts using different flip-angle evolution, 640/47) as well as on (c) axial reconstructed and (d) sagittal reconstructed three-dimensional T2-weighted images suspicious for LN metastasis, confirmed at histologic examination.
