SPECT (Single Photon Emission Computed Tomography) uses gamma rays to create 3D images, allowing for detailed views of blood flow and organ function. Gamma cameras, on the other hand, directly capture 2D images of gamma radiation emitted by radioactive tracers within the body, useful for initial scans. While both involve gamma rays, SPECT provides more detailed 3D images, aiding in more complex diagnostics.

FAQs & Answers

  1. What is SPECT imaging used for? SPECT imaging is commonly used to assess blood flow and function of organs, particularly in cardiology and neurology.
  2. How does a gamma camera work? A gamma camera captures 2D images of gamma radiation from radioactive tracers, providing preliminary insights into organ function.
  3. What are the advantages of SPECT over gamma cameras? SPECT provides enhanced 3D imaging capabilities, allowing for more detailed diagnostic information compared to gamma cameras.
  4. Are SPECT and gamma imaging the same? While both use gamma rays, SPECT offers more advanced imaging capabilities, delivering detailed 3D views, unlike traditional gamma imaging.
