Retreatment of the same lobe. A 60-year-old patient with retreatment of the right lobe. Day-7 post-retreatment axial T2-weighted MR image (a) and axial T1 FS contrast-enhanced MR image (b) show a slight volume increase of the treated lobe compared with the first procedure; the area of prostate necrosis presents two different intensity levels: the residual fluid cavity (arrowhead) and tissue necrosis (arrow), with less low intensity. Note, 6 months post first treatment axial T2-weighted MR image (c) corresponding to pre-retreatment aspect
