    Implementation of radionuclide scanning in medical science
    (2013) Ayesha Mohy-Ud-Din|A. S. Imran; Mashood Nasir
    A radionuclide scan is a way of imaging bones, organs and other parts of the body by using a small dose of a radioactive chemical. There are different types of radionuclide chemicals. The one used depends on which organ or part of the body is to be scanned. Gamma rays are similar to X-rays and are detected by a device called a gamma camera. The gamma rays which are emitted from inside the body are detected by the gamma camera, are converted into an electrical signal, and sent to a computer. A radionuclide scan is used for bone scan, tumor scan, cancer scan, kidney scan, lung perfusion scan, 'myocardial perfusion scan and thyroid scan etc. To detect the gamma photons usually a large crystal of sodium iodide is used in gamma camera. Different radionuclides used with their specific applications are summarized.
