I recently had a MRI confirm the presence of a small shadow in my lung, and subsequently a PET show abnormality (glow at that spot) at 3SUV. I have a history of long term bronchitis prior to this, and was told that there was the possibility the abnormality is due to infection.
However, I am perplexed as in how microbial organisms would show the same type of rapid metabolism characteristic of cancer cells. Basing upon the mechanism of PET, I'm not sure why the FDG would be readily taken in by the "causes" of this potential infection which would result in 3SUV. Essentially, I am asking if it is possible for viruses/etc. to speed up normal cell metabolism to a rate similar to tumor cells. I prefer not to get an biopsy if necessary.
Thank-you in advance.
