The figure shows a Gleason 3+4 prostate cancer (arrows) as identified on T2-weighted (A) and diffusion-weighted (B) MRI, F-18-choline PET (C), as well as PET/MRI (D).

NET circulating transcript and chromogranin A (CgA) levels in responders and non-responders. a) Transcripts were significantly reduced at 6-month follow-up compared to pre-treatment values. Non-responders (NR) exhibited significantly elevated levels at 6 months (FUP_6m). This was also significantly higher than in responders (R). b) A significant alteration was noted only for CgA in non-responders (NR) at 6 months. c) Pre-PRRT: NET transcript scores were elevated in 94 percent and CgA in 57 percent. d) Responders: NET transcripts decreased in 88 percent of responders (no change in 12 percent). CgA was unchanged in 47 percent, decreased in 21 percent and was elevated in 32 percent. e) Non-Responders: NET transcripts increased in 90 percent (no change in 10 percent). CgA was unchanged in 33 percent, decreased in 40 percent and was elevated in 27 percent. For NET transcripts, no falsely decreased or increased values occurred in responders or non-responders, respectively.
