Good info and thanks. Gives me some ammo to discuss with my oncologist. I've been concerned about radiation exposure from CT scans as I've had 14 of them since I was diagnosed with PACC last Aug. The excessive number is partly due to scans required when I was in a clinical trial at the NIH from which I've been released. I was always wondering why none of the scans were MRI, which from what I understand, do not expose a person to any radiation.

Thank you for this information! When my PC metastasized, my suddenly within normal limits tumor marker CA19-9 was rising but my CT showed no new growth. Drs insisted I was just panicking as they had told me just 3 months before I was cancer free ( so why didn’t I listen to them?). After reading comment from @markymarkfl and how he had kind of been in a similar until he got an MRI, I asked my dr if I could get an MRI and that’s when my 2 small liver lesions were found! And thus the next step was endoscopy with biopsy and so on. My question is do drs not know this information themselves?? They deal with a lot of patients; the usual progression after tumor (and maybe artery involvement and/or the abdominal peritoneum) is the liver. YOU may have to ask for that MRI and don’t delay is my humble advice.
