PET Scan - False Postives
My PET/CT scan from last week shows that my liver looks great. I had an RFA, which has been successful. My liver SUV score has dropped to zero over time.
However, the SUV at my lumpectomy (w/shrinking hematoma) site are rising over time (1.4, 1.9, 2.4). Last week, my value was 2.4 and a comment of "Malignancy Not Excluded, further testing required". My surgeon and Oncologist seem to think this is a false positive. If so, why the rising score? My lumpectomy was in 12/04. At surgical sites, is anyone else experiencing: 1. Rising SUV's? 2. Level SUV's? 3. SUV's slowly dropping and/or returning to zero? |
Margo,
If you suspect a false positive PET/CT scan results check if all precautions were taken at the time of the scan & the day before: 1. warm blanket : see http://her2support.org/vbulletin/sho...ht=warm+coffee 2. Prior day: no sugar, artificial sweeteners,fruits, carbohydrates. No exercize etc... (Precautions normally recommanded by radiology department) |
PET Scans - False Positives
Thank you for the information about the warm blanket. I will pass it on to the Nuclear Medicine department. I was wrapped in a blanket, though it was not warmed.
The day before my test I was allowed to eat only chicken and broccoli, and no food after midnight. It is a good thing I like broccoli :-) I am curious about my SUV's and the pattern that is occurring at the surgery site. Hopefully, I will receive some information from patients that are experiencing similar issues. Thank you again, Margo |
