Can you see scar tissue on pet scan?

A PET scan is primarily used to assess metabolic activity and detect cancer, rather than to visualize structural changes like scar tissue. While scar tissue may not be directly visible on a PET scan, it can sometimes affect the scan's results, potentially leading to increased metabolic activity in the area. Therefore, while scar tissue itself isn't typically seen, its presence may influence the interpretation of the scan. For better structural assessment, other imaging techniques like MRI or CT scans are often more effective.
