PET scans, or Positron Emission Tomography scans, are cutting-edge medical imaging tools that enable the visualization of molecular processes within the human body. In this comprehensive guide, we delve into the world of PET scans, their innovative use of molecular imaging, the procedure itself, their diverse applications in healthcare, and how they aid in the diagnosis and monitoring of various medical conditions.
1. Molecular Imaging: PET scans go beyond traditional imaging methods like X-rays and CT scans. They visualize metabolic and biochemical processes at the cellular and molecular levels.
2. Radioactive Tracers: PET scans involve the use of radioactive tracers, known as radiopharmaceuticals or radiotracers, which emit positrons. These positrons interact with electrons in the body, producing gamma rays that are detected by the PET scanner.
3. Diverse Applications: PET scans are used in various medical fields, including oncology, cardiology, neurology, and psychiatry.
