PET-CT examination: what is it?
The required amount of a radioactive substance that is safe for human health is injected into the patient's body. After that, the substance spreads through the circulatory system of the organism being examined. The radiation allows us to determine the overall picture and display it on a computer monitor.
The nature of the disease and the task of determination determine which substance is used to conduct the study: 11C-chlorin, 18F-fluorodeoxyglucose, 13N-ammonium, 11C-methionine. The last drug is prescribed when scanning a tumor in the brain.
