PET scanners

Glucose uptake detectors

PET scanners are medical imaging devices that detect gamma rays emitted by a radioactive tracer injected into the body.

PET stands for positron emission tomography.

The scanners produce three-dimensional images showing metabolic activity, helping diagnose cancer, heart disease, and neurological conditions.

Unlike CT or MRI, which show structure, PET reveals how tissues function: The PET scanner detected abnormal activity in her brain.
