Trainman, Good luck!! Check out MMS by Jim Humble. I have seen people stop the progression of Parkinsons, and get back SOME lost movement...but not 100% cured. But stopping the progression was huge.. Check it out.. it's a personal decision to go that route... There is some debate. I used it for other things and still use it. But not everyone trusts it.
PET scans can show up a cancer, it can reveal the stage of the cancer and also if the cancer has spread. Doctors recommend that patients with heart related conditions undergo a PET scan. It can reveal if parts of the heart have been damaged or scarred.
Actually although you are correct PET SCAN does do a great job, Doctors will recommend an angiogram, as a PET Scan is more expensive. For those wanting to avoid an invasive procedure ( angiogram) a PET scan is an alternative but not as definitive as an Angiogram.... this is my understanding anyways..
I found out that there is one in Santiago at the offices of Dr. Morel Diagnosis - Centro de Imgenes Mdicas - Laboratorio Clnico I don't think any English speaking person has found that out before because as you can see they do not refer to it as "Estudio PET" but "Gammagrafia".
