What is PET Scan used to find/ diagnose?

Cancer? Autoimmune disorders? Thyroid problems? Tumors? What can it identify?

Yes to all of the above. The focus is on it's use in diagnosing cancer, but it can be used to find many other structural anomalies in the human body.

CT scans usually make clearer pictures, but both take pictures of the inside of the body slice by slice to get a detailed look at what's going on. Or, in some cases, what's not going on.

They can also find obstructions in the gastrointestinal tract, hemorrhages in the brain, and any number of other things.
