Radionuclide imaging
Radionuclide Imaging
Radionuclide imaging (pronunciation: /ˌreɪdioʊˈnjuːklaɪd ˈɪmɪdʒɪŋ/), also known as Nuclear Medicine Imaging, is a medical imaging technique that uses small amounts of radioactive material to diagnose and determine the severity of a variety of diseases.
Etymology
The term "Radionuclide" is derived from the Latin word 'radius' meaning 'ray' and the Greek word 'nukleos' meaning 'kernel'. The term "imaging" is derived from the Latin word 'imago' meaning 'picture' or 'representation'.
Procedure
Radionuclide imaging involves the administration of a radionuclide into the body by injection, swallowing, or inhalation. The radionuclide travels through the body and emits Gamma Rays which are detected by a Gamma Camera to create images. The images can provide detailed information about the structure and function of organs, tissues, and bones.
Applications
Radionuclide imaging is used in various medical fields such as Cardiology, Oncology, Endocrinology, and Neurology. It is used to diagnose and manage the treatment of cancer, heart disease, gastrointestinal, endocrine, neurological disorders, and other abnormalities within the body.
