Post-biopsy haemorrhage in the midgland of a 69-year-old man with a PSA serum level of 4.7 ng/mL. a Axial T2-weighted fast spin-echo image (5525/109) and b axial fat saturated T2-weighted fast spin-echo image (5981/116) showing a large hypointense zone involving the left posterior site of the midgland and a smaller zone of low signal intensity in the contralateral side (white arrows). c The first axial perfusion gradient-echo T1-weighted image acquired before the injection of contrast medium displays diffuse high signal intensity in the midgland representing recent post-biopsy haemorrhage. d Gradient-echo T1-weighted subtracted image and e colour DCE MR map showing a real hypervascular zone in the left midgland, which appear smaller in size than in a, b and c. f Axial DWI image with b value = 1000 mm2/sec and g 3000 mm2/sec, and h ADC map showing mild diffusion restricted phenomena in the left posterior aspect of the midperipheral zone. Pathologic correlation after prostatectomy yielded prostate adenocarcinoma, with a Gleason score of 6 in left midland
