Meaning and Definition
A medical imaging device, specifically a PET (Positron Emission Tomography) scanner, which uses radioactive tracers to produce 3D images of functional processes in the body, such as metabolism or blood flow.
In a broader technological or scientific context, it can refer to any scanning device used on pets (animals), though this is a potential ambiguity and less common than the medical imaging meaning. The term is overwhelmingly a compound noun for the medical device.

FAQ
Frequently Asked Questions
No. A PET scanner images metabolic activity using radioactive tracers, while an MRI scanner uses magnetic fields to image anatomical structure.
A radioactive tracer (often attached to a sugar molecule) is injected. Active cells (like cancer cells) absorb more of it, making them visible on the scan.
While logically possible, this is highly ambiguous and non-standard. In professional contexts, it always means the medical device. For animals, one would say 'veterinary scanner' or 'scanner for pets'.
It involves a small amount of radiation, so it is used judiciously. The benefits of accurate diagnosis typically outweigh the risks. The radiation exposure is similar to several years of natural background radiation.
