Multiparametric MRI for Recurrent Prostate Cancer Post Radical Prostatectomy and Postradiation Therapy

Figure 2

Multiparametric-MR images of a 74-year-old man with prostate-specific antigen progression (PSA serum level 0.43 ng/mL) after radical retropubic prostatectomy, with suspected local recurrence. (a) Axial T2-weighted fast spin-echo image shows a solid nodular tissue of about 7 mm in size on the right posterior perianastomotic location in front of the rectal wall at about 12 mm from the ureteral meatus which is slightly hyperintense compared to pelvic muscles (white arrow). (b) Axial gradient-echo T1-weighted color map image showing a remarkable enhancement of the pathological tissue (white arrow). (c) Axial native DWI image at value = 3,000 s/mm2 showing marked restricted diffusion of water molecules (white arrow). (d) Axial ADC map reconstructed from images obtained at values of 0, 500, 1,000, and 3,000 s/mm2 shows a dark area corresponding to the abnormal hyperintense tissue seen on T2-weighted images and hypervascular nodule seen on color map (black arrow). All these findings are consistent with locoregional relapse.
