Scintigraphy

Scintigraphy

Scintigraphy is one of the diagnostic tests in the nuclear medicine, where radioisotopes are attached to few drugs which will travel to a specific organ or specific tissue are taken internally and the emitted gamma radiation is captured by external detectors which are also called as gamma cameras, it is to form two-dimensional images in a similar process to the capture of x-ray images.

It is also called as scintillography, it is an imaging method of nuclear events which are stimulated by collisions or charged current interactions among the nuclear particles or ionizing radiation and also atoms which result in a brief, localised pulse of electromagnetic radiation, usually in the visible light range. The localised pulse is generally identified and also amplified by a photomultiplier or by a charged coupled device elements, and its resulting electrical waveform is processed by computers to provide two- and three-dimensional images of a subject or region of interest.
