PET Scan, has anyone had one that was bright yellow and later found out that it was inflammation, no

Angela's PET scan showed bright yellow. Her doctor and California said the cancer was back. The doctor at Anderson said that inflammation can cause the PET scan to show bright yellow and said she had to have a biopsy to know for sure if the cancer is back. Does anyone know how common it is for a PET scan to show bright yellow and only be inflammation? Linda

    not sure
    I'm pretty sure is is very common that is why they don't want you to exercise before a pet scan and they keep you quiet and warm an hour before.

    PET - yellow area
    Yes, I had a CT scan last July and it had a yellow (sign of activity) My doc felt like it was inflammation from the surgery so we did a needle biopsy and sure enough that was what it was. The rest of the scan was clear.

    HUGS & PRAYERS
    So sorry to hear Angela is going through so much. The other ladies offered some good feedback. And I can agree that inflammation could be a cause of the highlighted areas. There's no doubt that inflammation can also cause a spike in the CA125 levels. Please get back to us and let us know what they find out.

    Till then, sending lots of prayers to all of you.

    Bright yellow???
    Not sure what that means.. they measure the pet scan by SUV.. standard uptake volume. The theory being that the cancerous cells are more active and will take up more of the radioactive glucose.. my mothr's gyn/onc. described it as sort of geiger counter reading . anything over 2.7 is most likely malignancy is what we were told..... what were Angela's SUV nos? Do you know?
    Anyhow, praying and hoping that the cancer isn't back....
    Hugs,

    In a PET scan they inject
    In a PET scan they inject glucose attached to a radioactive tracer. Cancer, normal fast-dividing cells, and "active" areas of the body eat up the glucose and thus take up the tracer. This causes what we call the "light up." On the color screen, it looks like a heat map where the brightest and hottest areas (red, yellows) -- represent the uptake areas.

    The highest concentration of these molecules will occur in areas of hypermetabolic activity, i.e., tumors, which will show up on the PET scan as bright yellow and white spots like a sunburst in an otherwise dark sky. Trauma to the tissues will also cause the PET scan to light up, so it makes sense that inflammation might look suspicious, as well.

    Hope you are well

    I know it was a long time ago but I just wonder what was the outcome of the scan, was the yellow areas cancer or just inflammation? Know of a similar misleading experience. Best wishes to you x
