What does moderate amount of physiologic activity present in the bowel mean on a pet scan?

A moderate amount of physiologic activity in the bowel on a PET scan typically indicates normal metabolic activity associated with digestion and bowel function. This can reflect the presence of glucose uptake by healthy intestinal tissues. However, it can also complicate the interpretation of potential abnormalities, as increased activity may sometimes mimic pathological processes. Further clinical correlation and additional imaging may be required for a definitive assessment.
