Screening, Nuclear Medicine Exam

How does the investigation work?

Metabolic processes inside the body are made visible 

The objective of diagnostic nuclear medicine is to make metabolic processes or the functional processes of a particular organ or tissue visible, and to recognise abnormalities at an early stage.
 
For this purpose low-level radioactive substances are used, which emit gamma rays as they decay (radionuclides). Usually the radionuclide technetium 99m (Tc-99m) is used. Depending on the organ to be examined, Tc-99m bonds with certain molecules that metabolise in the corresponding organ, are bound, or at least absorbed in that organ.
 
In general, the radioactive substances are injected into a vein in the arm and carried with the bloodstream to the organ to be examined. Once in the organ these substances are incorporated into the metabolic processes, accumulate and hence "mark" the specific metabolic process.

Measurement of the radiation with a gamma camera 

The radiation released in the body is measured by a gamma camera. Then a computer electronically processes the measurements and converts these into an image (scintigram). These images then allow for accurate assessment of the investigated function / metabolic process of the depicted organ.
