Definition


Scintigraphy is a medical imaging technique performed solely in nuclear medicine. It consists of injecting the patient with a radioactive substance, administered to an organ or tissue, which emits radiation as it circulates enabling certain areas to be highlighted and recorded by a special camera, which then constructs a visual map of the area under investigation. There are a number of different types of scintigraphy, including bone, pulmonary, cardiac, and more. This procedure inflicts no harm on the body, as the radiation doses are extremely low, and can thus enable a number of conditions to be detected. It is notably used to investigate bone metastases in cases of cancer development, pulmonary embolism in the lungs, or the function of certain organs, such as the heart's vascularization capacity in myocardial scintigraphy or that of the kidneys in renal scintigraphy.
