Study Notes

What is Nuclear Medicine

  • A medical specialty that uses small amounts of radioactive materials to diagnose and treat diseases.
  • Provides information about the function of organs and tissues, unlike other imaging techniques that capture images of the body's structure.

Radiopharmaceuticals

  • Medicinal formulations that contain radioactive isotopes, used in nuclear medicine.
  • Key component: Radioactive Isotopes (Radionuclide), which emit radiation that can be detected or used for therapeutic effects.
  • Carrier Molecule: A biologically active molecule or chemical that delivers the radioactive isotope to specific organs, tissues, or cells within the body.

Purpose of Radiopharmaceuticals

  • Diagnostic: To diagnose diseases.
  • Therapeutic: To treat diseases.
  • Theranostic: A combination of diagnostic and therapeutic purposes.

Imaging Techniques

  • SPECT (Single Photon Emission Computed Tomography)
  • PET (Positron Emission Tomography)
  • Hybrid: Fuses the image of both modalities, e.g., PET/CT, SPECT/CT, PET/MRI

Nuclear Physics

  • A branch of physics that studies the atomic nucleus and its interactions.
  • Explores the fundamental properties of nuclei, including their structure, behavior, and the forces that govern their interactions.

Types of Radiation

  • Alpha Particles
  • Beta Particles
  • Gamma Rays

Decay Processes

  • Radioactive decay: Alpha, beta, and gamma decay.
  • Half-life concept: The time required for half of the radioactive atoms in a sample to decay.

Nuclear Reactions

  • Transformations of atomic nuclei that involve changes in their composition.
  • Types:
    • Fission: Atomic nucleus splits into several parts, creating energy (e.g., nuclear reactors).
    • Fusion: Two light atomic nuclei combine, creating nuclear energy (e.g., stars).
    • Radioactive decay: Unstable atom undergoes radioactivity to become stable.

Radiation Safety

  • Principles of radiation protection: Time, Distance, Shielding.
  • Monitoring and controlling exposure to radiation.
  • Regulatory bodies:
    • IAEA (International Atomic Energy Agency)
    • NRC (Nuclear Regulatory Commission)
    • PNRI (Philippine Nuclear Research Institute)
    • CDRRHR (Center for Device Regulation, Radiation Health, and Research)

Best Practices and Waste Management

  • Proper handling and disposal of radioactive materials.
  • Training for healthcare professionals.
