      Cancer diagnosis and treatment can have a gazillion permutations. There really are no one size fits all protocols. Ask you oncologist what he expects to learn from the scans that he has ordered.

      My understanding was the PET scan was used after treatment to find out whether there was tumor growth activity. CAT scans were used for tumor location and size. Ask your oncologist for more clarity.

      I only had one PET scan and it was to see if any other cancer cells were floating around after my initial diagnosis. Now I only have CT scans like you do. I will be having one a year for the next 3 years.

      I found this on Cleveland Clinic's web site:
      One of the main differences between PET scans and other imaging tests like CT scan or magnetic resonance imaging (MRI) is that the PET scan reveals the cellular level metabolic changes occurring in an organ or tissue. This is important and unique because disease processes often begin with functional changes at the cellular level. A PET scan can often detect these very early changes whereas a CT or MRI detect changes a little later as the disease begins to cause changes in the structure of organs or tissues.
