I think a Pet scan can cover a broader area. I had a pet scan when first diagnosed to see if there were any other areas in question. I think if the pet scan showed anything other than what we already knew, my onc would have ordered more tests to varify the findings. Now, if I have a concern my onc usually orders an X-ray or CT because we are looking at a particular area in question and not trying to get a picture of the whole body. My onc is also of the opinion that scans should be done if there is an area that is symptomatic. I was in a study at the time of my treatment that used MRI's mostly and I am not sure what the significance of that was. I personally think I would go "bonkers" if I had routine scans!
