A 66-year-old man with a serum PSA of 14.3 ng/mL. Axial T2-weighted imaging (a), ADC map (b), and calculated b = 1500 s/mm2 image (c) showed a lesion in the left mid TZ (asterisk in a, b, c). In addition, note a BPH nodule in the right mid TZ (long arrow in a, b, c) and an ectopic BPH nodule in the left mid PZ (short arrow in a, b, c). Computer-aided diagnosis map overlaid on the T2-weighted image (d) showed a high cancer probability within the left mid TZ lesion (dashed arrow), whereas it showed low cancer probability within the right mid TZ BPH nodule (long arrow) and the ectopic BPH nodule in the left mid PZ (short arrow). Final pathology revealed a Gleason 7 (3 + 4) prostate cancer within the left mid TZ lesion (image courtesy of Dr. Baris Turkbey and Dr. Stephanie Harmon from Molecular Imaging Program, NCI, NIH, Bethesda, MD, USA)
