Can you please describe the difference btwn. a PET & CAT scan?

My mother had CK procedure in June and she wanted to know if
either would show scar tissue (vs. tumor) ?

Also after CK do most/some return to Chemo treatments?
What determines the need to start it again?

Some patients may continue with chemotherapy after CK depending upon the circumstances. A PET scan would be helpful in distinguishing scar tissue from tumor as it shows the metabolic activity of the area whereas CT only shows the anatomy (structure). CT scans show more detailed structure but not whether something is actively growing and dividing or not. Often they are combined into a PET/CY scan to derive the benefits of both scans at once.
