Thanks for taking the time to research that for me...
I've been overwhelmed since my original diagnosis, surgery, and the ups and downs the Dr/pathologists have put me through. I will ask my Gny/Onc to do both to compliment each other.
I just did some research....I googled "CT scan or Pet scan" and got this info;
PET and CT are both standard imaging tools that allow physicians to pinpoint the location of cancer within the body before making treatment recommendations.
The highly sensitive PET scan detects the metabolic signal of actively growing cancer cells in the body and the CT scan probides a detailed picture of the internal anatomy that reveals the location, size and shape of abnormal cancerous growths.
Alone , each imaging test has particular benefits and limitations but when the results of PET and CT scans are "fused" together, the combined image provides complete information on canacer location and metabolism.
The bottom line is that you can have both scan - PET andCT - done at the same time.
I hope this helps a little bit.
Peace.
