I had a PET that showed two spots on my upper lungs (1 each) I thought they might be from an infection but my ENT felt they where cancer for sure. The biopsy showed inflamation but was concidered inconclusive because of some bleeding during the procedure.
Latest PET showed no activity in those areas so I can say from my perspective that inflamation can give a false positive that will fool an ENT at the least.
