PET-CT, or Positron Emission Tomography-Computed Tomography, is a medical imaging technique that combines two different imaging modalities: PET and CT. 1. **Positron Emission Tomography (PET)**: This technique uses a small amount of radioactive material (radiotracer) that is injected into the body. The radiotracer emits positrons, which are detected by the PET scanner to produce images that reflect the metabolic activity of tissues.
