PET-CT scan facilitates the interpretation of the results of the radionuclide method by providing the anatomical picture obtained by CT.

PET CT opens up new possibilities in the precise diagnosis of tumors, and in one procedure, in addition to a more precise localization of the primary tumor, it allows you to obtain detailed information about the state of other organs and systems.

PET-CT scan takes about 30-40 minutes. All this time, patient can not move, therefore, problems associated with being stationary (pain in the joints or bones, swelling, cramps, tremors, etc.) must be reported to the doctor in advance. Specialists will select the optimal examination mode. The procedure itself consists of injecting a special preparation (an hour and a half before the tomography), labeled with an isotope, and subsequent scanning of the whole body using PET-CT device. The procedure is painless. The radioactive isotope 18-fluorine is rapidly excreted from the body, therefore PET-CT examination is safe for health. For the speedy removal of the drug from the body, patient should drink more distilled non-carbonated water after the procedure.

What is the purpose of this study?

In recent years, the PET-CT study has become a leading diagnostic tool for various types of cancer. Using this scan, the degree of spread of the tumor process in the body is determined, the response to therapy is evaluated, and observation is carried out. In addition, PET with FDG has been shown to be highly effective in detecting infections. This type of scan is also used in neurological examinations for epilepsy and degenerative brain diseases.

How is the procedure conducted?

After completing the necessary documentation, patient will be taken to treatment room, where blood will be taken to determine the glucose level and anthropometric data (height and weight) will be measured. If the blood sugar level is within acceptable values, nurse will take you to changing room.

Petient takes a comfortable position, and an intravenous catheter is applied;
Every 15 minutes it is necessary to drink a glass of contrast water for 60-90 minutes (just need to drink 1 liter);

After the introduction of the radiopharmaceutical, patient needs to remain in a calm, relaxed, stationary position, not to talk. If necessary, it is allowed to go to toilet 20-30 minutes after the administration of the radiopharmaceutical.

In the waiting area it is not recommended to talk, use a mobile phone. The need to fulfill all the requirements determines the quality (uniform distribution and to avoid unwanted accumulation of radiopharmaceuticals) of the radionuclide study conducting;

90 minutes after the administration of the radiopharmaceutical, patient will be invited to PET / CT examination room. Empty the bladder before scanning.

The duration of the study varies from 15 to 30 minutes. All this time it is necessary to lie calmly without movement. Movements during the scan lead to artifacts that may make it difficult or impossible to describe the results of the study.

Due to the properties of the radiopharmaceutical used in the study, it is necessary to come to the department at a strictly scheduled time. Refusal of the planned procedure should be done in 24 hours - no later.
