PET stands for Positron Emission Tomography which is a research method that shows the chemical metabolism and function of organs or tissue elements.
The ability to superimpose the image, so-called image fusion between MRI images and PET image brings anatomical situation information and information on the metabolism.
With the PET method, differences in tissue metabolism, function and circulation can be discovered. Diagnoses can be made earlier than with other methods such as CT and MRI. The PET method shows the spread of malignant tumors and metastases. Epilepsy that cannot be treated with drugs may instead be treated surgically. PET examination can be quite precisely demarcate the area to be treated.
During a PET scan, areas of the parietal and temporal lobes´ metabolism can be studied in connection with, for example Alzheimer´s.
PET examination can depict blocked or narrowed arteries. The method can show areas where blood flow is elevated or abnormal.
