Definition Positron emission tomography (PET) is a special imaging examination procedure that can be used to visualize metabolic processes in the body. For this purpose, the patient is administered low-level radioactive glucose via the vein, made visible with a measuring unit and the information is processed into a spatial image. The sugar is distributed throughout … Positron emission tomography (PET)
Functionality of PET In positron emission tomography, good preparation and compliance with various measures are crucial for good image quality and informative value. Current blood values (especially kidney, thyroid and sugar values) must have been determined in advance. On the day before the examination, any physical exertion must be avoided. In addition, no more food … Functionality of PET | Positron emission tomography (PET)
Evaluation of the images The particles released during positron emission tomography are detected by a special detector. A connected computer calculates the incoming information and generates an image that shows the metabolic activity. Areas with high activity are displayed brighter than those with low activity. Some organs such as the brain or the heart naturally … Evaluation of the images | Positron emission tomography (PET)
