Diffusion-Weighted Magnetic Resonance Diagnosis of Local Recurrences of Prostate Cancer after Radical Prostatectomy: Preliminary Evaluation on Twenty-Seven Cases
Figure 3
DWI, false negative. Patient with a glandular apical residual prostate tissue and a progressive increase of PSAt (last value before DWI: 0.61 ng/mL). The T2-weighted image (a) shows the minimal residual prostate tissue with a small bulging in the right paramedian site (arrow). No detectable hyper intensity was visualized in DW image (score DWI = 0, (b)); 18F-choline PET-CT (c) showed a focal uptake at the site of the described bulging. The post-RT decrease of PSAt under 0.2 ng/mL was a further standard of reference in this case.
