nukleaarilääketieteellinen

Nukleaarilääketieteellinen refers to the field of nuclear medicine, which utilizes radioactive substances, also known as radiopharmaceuticals, to diagnose and treat diseases. This branch of medicine employs small amounts of radioactive materials that are either injected into the body, swallowed, or inhaled. These substances travel to specific organs or tissues, emitting radiation that can be detected by specialized imaging equipment like PET (positron emission tomography) or SPECT (single-photon emission computed tomography) scanners. The images produced provide detailed information about the function of organs and tissues, helping physicians identify abnormalities that might not be visible with other imaging techniques.

Beyond diagnostic imaging, nuclear medicine also plays a significant role in therapy. Certain radioactive isotopes are used to target and destroy diseased cells, such as cancerous tumors. This form of treatment, known as radiotherapy or radionuclide therapy, delivers radiation directly to the affected area, minimizing damage to surrounding healthy tissues. The applications of nuclear medicine are broad, encompassing cardiology, oncology, neurology, endocrinology, and infectious diseases. It is a powerful tool for early detection, precise diagnosis, and effective treatment of a wide range of medical conditions.
