Médecine Nucléaire et Radio-isotopes

Médecine Nucléaire

• Focuses on the use of radioactive materials, or radioisotopes, in diagnosis and treatment.
• Employs imaging techniques to visualize the body's internal structures and functions.
• Involves the application of nuclear physics principles for medical purposes.

Radio-isotopes

• Radioactive isotopes used in medicine for various applications.
• Characterized by unstable atomic nuclei undergoing radioactive decay.
• Emit ionizing radiation that allows for detection and visualization of biological processes.
• Different isotopes exhibit different types and intensities of radiation crucial for specific applications.
• Examples include technetium-99m, iodine-131, and fluorine-18.

Diagnostic Par Imagerie

• Utilizes radioactive tracers to obtain images of internal organs and tissues.
• Allows for non-invasive visualization of physiological processes.
• Techniques include SPECT (Single Photon Emission Computed Tomography) and PET (Positron Emission Tomography).
• SPECT visualizes the distribution of gamma-emitting radiotracers.
• PET detects positrons emitted by radiotracers, enabling detection of metabolic activities, and providing high-resolution images.
• Images guide doctors in evaluating organ function, identifying diseases, and monitoring treatments.

Thérapies Ciblées

• Uses radioactive isotopes to target specific cells or tissues.
• A type of medical treatment aimed at destroying cancerous cells with minimal damage to surrounding healthy tissues.
• Relies on the selective uptake of radioactive compounds by the diseased cells or tissues increasing their exposure to radiation.
• Examples include radio-iodine therapy (for thyroid cancer) and targeted alpha therapy.

Physiologie Et Anatomie Nucléaire

• This branch examines functional anatomy through radioactive isotopes.
• Provides valuable information about physiological processes.
• Enables researchers to study organ and tissue function in vivo.
• Tracks the movement and distribution of tracers in the body to measure organ function and detect abnormalities.

Éthique En Médecine Nucléaire

• Addresses the ethical concerns related to the use of radioactive materials.
• Includes radiation safety protocols to protect healthcare professionals and patients.
• Covers the ethical considerations of isotope use in diagnosis and treatment.
• Safe handling of radioactive materials and disposal are essential aspects.
• Issues concerning patient consent, radiation risks, and potential societal impacts must be considered.
• Ethical concerns regarding the distribution and accessibility of these treatments should be considered.
• Considerations for the potential misuse of technologies and the need for strict regulations should also be included.
