radionuclide imaging
Quick Summary
Radionuclide imaging, a key component of nuclear medicine, uses radioactive isotopes to diagnose and treat diseases. This medical specialty allows for non-invasive visualization of molecular activity within the body, aiding in early disease detection and monitoring treatment responses.12
The process involves introducing a radioisotope into the body, typically via injection. This isotope is absorbed by different organs in varying amounts. Radiation emitted by the isotope is then detected, allowing clinicians to map its concentration and identify abnormalities in organ size and shape. Techniques like positron emission tomography (PET) and single photon emission computed tomography (SPECT) are advanced methods used in this field. For example, iodine-131 concentrates in the thyroid gland, helping to diagnose thyroid function issues.1345
