PET radiotracers

PET radiotracers are specialized slightly radioactive substances used in positron emission tomography (PET) scans to visualize and measure biological processes in the body. They are designed to target specific molecules or tissues, such as cancer cells or brain activity, by mimicking natural compounds. When injected into the body, the radiotracer emits signals detectable by the PET scanner, creating detailed images that help diagnose diseases, monitor treatment responses, or study organ function. Their precision and ability to highlight specific physiological activities make PET radiotracers valuable tools in modern medical imaging.
