The PET scan uses a low-dose radioactive tracer (dye) to enable certain parts of the body where cell activity is higher than normal to show up in imaging. When the two tests are combined, doctors can glean a great deal of information to help them diagnose or rule out a condition without the need for more invasive procedures. A PET-CT scan may also be used during the course of treatment for certain conditions, such as cancer, to determine if treatments are working.
