Q: What is the difference between a PET/CT scan and a CT scan?
A: A PET scan measures chemical activity in the body such as cells and metabolic changes. A CT scan analyzes your body's anatomy such as organs, bones and soft tissue.
Q: Does my insurance require pre-certification for radiology procedures?
A: It depends on the provider. Medicare does not but some providers such as Humana does so check with your provider to be safe.
Q: Is the PET/CT scan safe?
A: Yes. The risks associated with a PET scan are very minimal. The quantity of radiation is low and the FDG degrades quickly so that no detectable radioactivity is present after several hours.
Q: Is the CT scan safe?
A: Yes. You receive a minimal amount of radiation comparable to that of an x-ray.
Q: What happens after the exam(s)?
A: After your scan, you will get up from the scanner bed and check out with the receptionist. You can resume your normal diet.
Q: When will I know the results?
A: It usually takes 1 to 3 days for the results to be processed.
