Information
Positron emission tomography (PET-CT)
A PET-CT scan – positron emission tomography combined with computed tomography – is an innovative diagnostic imaging method that enables a quick, painless and safe examination of the patient’s body. Before the scan, the patient is given an intravenous injection of a substance known as a radiopharmaceutical, most commonly 18F fluorodeoxyglucose (FDG). The radioactive fluorine isotope contained in this substance has a short half-life, ensuring that the radiation dose is safe for the patient.
The metabolism of fluorodeoxyglucose is identical to that of glucose and is much more active in cancer cells than in healthy cells; this enables the localisation and early detection of the disease, even before structural changes become apparent. During a whole-body scan, a PET scan is performed simultaneously to show the uptake of the tracer accumulated in the body, alongside a CT scan, which visualises the body’s anatomical structures. The combination of these two methods (PET-CT) allows for a very accurate assessment of the metabolic changes occurring in cells, as well as the identification of disease foci and the determination of their location.
PET-CT scans are mainly used in the diagnosis of cancer, as well as in certain cardiac and neurological conditions. In some cases of cancer, they enable a definitive diagnosis to be made, something which was difficult to achieve using other imaging techniques.
Połączenie metod PET i TK umożliwia obrazowanie zarówno własności anatomicznych jak i czynnościowych badanego narządu, pozwalając na diagnostykę patologii na poziomie komórek, co ma szczególne znaczenie dla identyfikacji wczesnych zmian nowotworowych. Badanie umożliwia lokalizację ogniska pierwotnego niektórych nowotworów, oceny ich zaawansowania, ewentualnie ocenę wznowy procesu chorobowego. W niektórych typach nowotworów daje możliwość oceny skuteczności stosowanego leczenia np. chemioterapii, dzięki temu możliwa jest ewentualna zmiana schematu leczenia. Umożliwia również planowanie radioterapii, przeprowadzanej pod kontrolą PET. Istotną informacją jest możliwość oceny drobnych zmian, które nie są możliwe do zobrazowania za pomocą innych technik radiologicznych.
