1. Understanding PET Scans in Veterinary Medicine

Positron Emission Tomography (PET) scans represent a significant advancement in veterinary diagnostics, offering a unique perspective on the internal workings of animals. Unlike traditional imaging techniques such as X-rays, CT scans, and MRIs, which primarily focus on anatomical structures, PET scans delve into the functional and metabolic processes occurring within the body. This capability enables veterinarians to detect diseases at an early stage, often before structural changes become apparent.

1.1. The Science Behind PET Scans

PET scans rely on the administration of a radiotracer, a radioactive substance that emits positrons. These positrons interact with electrons in the body, producing gamma rays that are detected by the PET scanner. The scanner then creates a 3D image based on the distribution of the radiotracer, highlighting areas of high metabolic activity. This is particularly useful in identifying cancerous tumors, which tend to exhibit increased glucose uptake compared to normal tissues.
