Question: interpreting pet scan results

 r2000 - Mon Dec 24, 2007 9:39 pm

I had a total tyroidectomy to treat thyroid cancer, followed by RAI 150 mci in May 2007. A chest CT in Oct 07 showed an enlarged thymus gland but no other metastases. A recent PET scan done last week reports "diffuse thymic FDG activity, with SUV max of 2.9." What does this mean? Is cancer suspected?

User avatar Hi r2000,

PET scans are a relatively new imaging modality. Their use is currently basically limited to cancer evaluation at this point with a few other exceptions.

I am certainly not an expert in interpetation of these scans; however, my understanding is that diffuse uptake means that the entire thymus area has taken up the tracer evenly which would be indicative that there are no "hot spots" that may be indicative of cancer spots in the thymus.

I would recommend you follow up with your oncologist about this but I believe this is a good finding.

Best wishes.
