Radionuklidscintigrafi

Radionuklidscintigrafi is a medical imaging technique that uses small amounts of radioactive materials, called radiotracers, to visualize and assess the function of organs and tissues. In this procedure, a radiotracer is administered to the patient, typically through injection, inhalation, or ingestion. The radiotracer emits gamma rays, which are detected by a special camera known as a gamma camera or a SPECT scanner.

As the radiotracer travels through the body, it concentrates in specific organs or tissues depending on its chemical properties and the biological processes being studied. The gamma camera captures the distribution of the radiotracer, creating images that show how well an organ is functioning or if there are any abnormalities. This allows doctors to detect diseases at an early stage, determine the extent of a disease, and monitor the effectiveness of treatment.

Radionuklidscintigrafi is a non-invasive procedure that provides valuable functional information, complementing anatomical details obtained from other imaging modalities like X-rays or CT scans. It is used in a wide range of clinical applications, including cardiology to assess blood flow to the heart, neurology to study brain activity, and oncology to detect and stage cancer. The amount of radioactivity used is very low, ensuring patient safety.
