Nuclear medicine utilizes radioactive materials to diagnose and treat diseases, with its applications spanning imaging, therapy, and research. This branch of medicine allows doctors to see inside the body and target specific areas for treatment, using techniques that are both precise and effective.

Nuclear medicine procedures are revolutionary because they provide functional information about the body. Unlike X-rays that show structure, nuclear medicine reveals how organs and systems are working. This functional imaging helps doctors detect diseases earlier and more accurately. Radiopharmaceuticals, radioactive drugs, are key in this process. These substances emit gamma rays that are detected by special cameras, creating images that highlight areas of disease. Additionally, nuclear medicine is used in therapy to target and destroy cancer cells with radiation. This targeted approach minimizes damage to healthy tissues, making it a preferred option for certain types of cancer.

1.1. What Are Radiopharmaceuticals and How Do They Work?

Radiopharmaceuticals are radioactive drugs used in nuclear medicine for both diagnosis and therapy, functioning by emitting radiation detectable by imaging devices or directly targeting diseased tissues. These compounds combine a radioactive isotope with a pharmaceutical agent, allowing them to be tracked within the body.

The magic of radiopharmaceuticals lies in their dual action. First, the pharmaceutical component ensures that the radioactive isotope accumulates in the specific area of interest, such as a tumor or organ. Once there, the radioactive isotope emits gamma rays, beta particles, or alpha particles. Gamma rays are used for imaging, allowing doctors to see the location and extent of the disease. Beta and alpha particles, on the other hand, are used for therapy. They deliver a localized dose of radiation that destroys diseased cells while sparing healthy tissue. The choice of isotope and pharmaceutical agent depends on the specific medical condition being investigated or treated. For example, iodine-131 is used to treat thyroid cancer because the thyroid gland naturally absorbs iodine. Similarly, technetium-99m, attached to various agents, is used in bone scans, heart scans, and other diagnostic procedures.
