What is PET?
Positron Emission Tomography (PET) is a functional imaging technique that visualizes metabolic processes in the body using radiotracers.
It is commonly used to detect abnormalities in the brain, such as changes in glucose metabolism or receptor activity.
How PET Works:
- Radiotracers (e.g., FDG-F18) are injected into the bloodstream and emit positrons.
- Collisions between positrons and electrons produce gamma rays, which are detected by the PET scanner.
- This data is used to construct detailed 3D images of metabolic activity.
