SUV decrease from original PET

My first PET showed an SUV of 52.5.  The recent PET report (2 months after chemo and radiation treatments) shows SUV of 2.3.  I assume this is a good thing but do not have an appointment with my oncologist for another week.  Just wondered if anyone knows if a decrease means inflimation or if cancer is still there.

    I am sorry we were never given those numbers

    for my husbands scans. I always recommend going straight to the dr anyways for answers like these to ensure you get the right answer. Please let us know and good luck!

    Lower SUV could be very good news.

    Since SUV measures metabolic activity at a molecular level this is very good information for you.  It can indicate a reduction in the size of the lesion and the number of cancer cells.  To get a better idea of the amount it has shrunk you need to have a thoracic CT.  My best hopes nderstanding is that this is great news.
