A 75-year-old man with prostate carcinoma treated remotely with external beam RT, presenting with biochemical relapse. Pelvic MRI was performed using phased array surface coils. Axial T2 TSE images (a) demonstrate typical findings following RT in the pelvis with low T2 signal and atrophy of both the prostate and small seminal vesicles (SV) when compared with pre-treatment imaging (not shown). Also note the poor differentiation of the prostate zonal anatomy. There is an amorphous area of lower T2 signal intensity diffusely in the left gland (open white arrow). DWI with calculation of ADC map (b) reveals a corresponding area of markedly restricted diffusion throughout the left gland (open white arrow) that represents biopsy proven recurrent tumour in this patient
