PET-CT of the abdomen: what the examination will show
Positron emission and computed tomography today is a unique, unparalleled examination method. It is used to detect cancer. Vital organs are located in the abdominal cavity. Any of them may be affected by a cancerous process. Even an experienced oncologist is not able, without additional research, to determine where the tumor is located and how metastases spread. Biopsy and histology allow you to identify the structure of the neoplasm, select therapy. But they do not give exact information about its location and size. In addition, these are invasive research methods. An advanced non-invasive method is PET-CT, which increases the accuracy of biopsy, giving the most accurate informational picture of what is happening.
For research, the patient is injected with the drug FDG - fluorodeoxyglucose. It contains glucose labeled with radionuclides. The substance has practically no contraindications, is well tolerated, has a short half-life.
Contraindications to the method are:
- Pregnancy and breastfeeding.
- Decompensated diabetes mellitus, with a blood glucose level above 11.0 Mmole.
- Renal and hepatic impairment.
- Recently transferred surgical interventions.
- Radiation and chemotherapy.
Positron emission tomography, despite its relatively short period of use in clinical practice, has been proven to be safe. The isotope is quickly removed from the body, and the radiation exposure does not exceed the permissible limits. The procedure consists of two stages. On the first person, a radiopharmaceutical is administered. For it to spread correctly, it is important for the patient to remain calm during this period. You can't read, talk, listen to music. At the second stage, the scan takes place directly in the tunnel of the tomograph.
This check requires some preparation:
- The examination is carried out on an empty stomach.
- Alcohol and alcohol-containing substances must be excluded within 48 hours.
- Remove carbohydrates from the diet per day: flour, sweet, cereals, milk, sugar, fruits, vegetables.
- Drink more clean, still water at room temperature.
