It is funny Riley as I thought that a PET scan was really cutting edge stuff compared to a CT scan. The reason I had both to further the story is that a CT scan, I'm told, can't find tumors in your arm, only your torso. So I needed the PET scan to see clearly what might be going on in my arm. Weird eh?But yes, to learn that as expensive as a PET scanner is, for cancer tumors the resolution is only good enough to light up a tumor if it is at least 1 cm in size. Anything smaller and apparently we don't have the equipment for that. Not a problem really if it is skin cancer and the tumor lies at the surface and you can feel or see it but if you're looking for something below the skin you're hooped until it gets large enough.................
