nukleärmedicinsk

Nukleärmedicinsk is a medical specialty that uses radioactive substances, known as radiopharmaceuticals, to diagnose and treat diseases. This field combines principles of nuclear physics, chemistry, biology, and medicine. Diagnostic procedures in nuclear medicine typically involve administering a radiopharmaceutical to a patient, either by injection, inhalation, or ingestion. This substance then travels to specific organs or tissues in the body. Detectors, such as gamma cameras or PET scanners, are used to capture the radiation emitted by the radiopharmaceutical, creating images that reveal the function and metabolism of these areas. This allows for the early detection of abnormalities that might not be visible with other imaging techniques.

Therapeutic applications of nuclear medicine involve using radiopharmaceuticals to deliver targeted radiation doses to diseased cells, primarily for cancer treatment. These radioactive substances are designed to concentrate in specific areas, such as tumors, where their radiation can damage or destroy cancer cells while minimizing damage to surrounding healthy tissues. Examples of such treatments include radioactive iodine therapy for thyroid cancer and radioisotope therapy for certain types of lymphoma and bone metastases. The field of nuclear medicine is continuously evolving with the development of new radiopharmaceuticals and imaging technologies, offering increasingly precise diagnostic and therapeutic options for a wide range of medical conditions.
