PET-CT uses human metabolites such as glucose analog 18F-FDG as the imaging agent, and reflects the metabolic changes through the amount of imaging agent absorbed by the lesion site. Mildly elevated metabolism can be seen in inflammation, tumors, traumas, and sports interference.
1. Mildly elevated PET-CT metabolism can be seen in inflammation, such as lymphadenitis, tonsillitis, etc., which can be manifested as mildly elevated PET-CT metabolism.
2. Although the glucose metabolism of most malignant tumors is significantly higher than that of normal tissues, some malignant tumors, such as multiple myeloma and benign neoplastic lesions, may also show mildly elevated PET-CT metabolism.
3. Failure to fast before the examination, trauma, exercise, etc. will interfere with glucose uptake and imaging, resulting in “false-positive” results, which will be manifested as mildly elevated PET-CT metabolism.
Mildly elevated metabolism on PET-CT suggests that a certain part of the metabolism is active, and the specific reasons need to be combined with your own situation, so go to the hospital and be analyzed by the doctor to clarify the reasons, so as to avoid delaying your condition.
