PET stands for positron emission tomography, and this generally uses a safe radioactive tracer molecule called 18F-fluoro-2-deoxy-D-glucose (FDG). Fortunately, that’s not on the quiz — you don’t need to know it. All that is worth knowing is that PET scans offer “metabolic imaging”, which detects differences in the metabolism of tissues. [...]
