 This is actually something that I've tried to explain on my channel too, and I think people have misinterpretations due to just what a PET scan is. You're using a radioactive form of glucose, which when it's absorbed by cells, literally all cells in your body utilize glucose to some extent, especially your brain, very metabolic tissues like your heart, your muscle tissue. So technically in a PET scan, everything is literally glowing, but the final image that patients see from a PET scan is something that's processed. So they actually reduce the background noise from every cell in your body that's glowing to some extent to find the cells that are glowing a little bit more than the other cells in the proximity to find where the tumors are. So those final images that people see of PET scans are processed, but at the core of it, all cells in your body utilize glucose to some extent. We're just utilizing image processing methods to try and find and pinpoint where the tumors are, where the cells that are utilizing glucose more than cells in the neighboring environment.
