From: Beyond diagnosis: is there a role for radiomics in prostate cancer management?
Seventy-two-year-old patient who underwent radical prostatectomy for prostate cancer (at pathology, Gleason score 3 + 4). Staging MRI shows a large peripheral zone (left posteromedial) lesion with intermediate signal on T2-weighted images (a, lesion epicentre marked with white star), focal and marked hypointensity on the ADC map (b, red region of interest) and corresponding hyperintensity on high b value DWI (c, white arrowhead). Three years after treatment, rise of PSA value determines biochemical recurrence. [68Ga]Ga-PSMA-11 PET/CT (d and e) shows a small but concerning right external iliac lymph node.
