PET scan
Radioactive glucose imaging
A PET scan is a medical imaging procedure that detects gamma rays emitted by a radioactive tracer injected into the body.
PET stands for positron emission tomography.
The scan reveals metabolic activity in tissues, making it especially useful for detecting cancer, heart disease, and brain disorders: The PET scan showed no signs of tumor recurrence.
