PET/CT SCAN

Positron emission tomography combined with X-ray computed tomography of the whole body with PET/CT with [¹⁸ F]-FDG

PET/CT is a high-tech alternative method of radiation diagnostics, both complementing traditional imaging methods (CT, MRI, ultrasound, etc.) and, in some cases, fully replacing them. The main radiopharmaceutical for PET/CT used in oncology is [18F]-fluorodeoxyglucose or [18F]-FDG – radiolabeled glucose analog. Accumulation of [18F]-FDG in PET/CT in organs and tissues is proportional to the degree of glucose metabolism, which is elevated in the cells of most types of malignant tumors. Thanks to this, PAT/CT with [18F]-FDG allows you to identify the tumor process, determine its prevalence, plan and evaluate the effectiveness of treatment.

General indications for PET/CT with [¹⁸ F]-FDG in oncology and hematology:

Differential diagnosis of benign and malignant tumors.
Search for a primary tumor focus in the presence of metastases from the NGO (CUP syndrome) and in patients with paraneoplastic syndrome.
Staging of the established tumor process.
Evaluation of the effectiveness of treatment of the established tumor process.
Assessment of the nature of residual changes on the background of the treatment.
Detection of recurrence of the tumor process, including with an increase in the level of tumor markers.
Selection of the most informative site for biopsy in the tumor focus.
Planning radiation therapy.

Absolute contraindications for PET/CT with [¹⁸ F]-FDG does not exist, there are relative contraindications:

pregnancy (the decision to conduct a study is made by a medical council);
acute pathological condition;
severe somatic condition, including a condition that does not allow to be in a static supine position for 60 minutes;
infectious or inflammatory process in the acute (active) phase;
hyperglycemia (blood glucose levels above 11 mmol/l);
conditions that do not allow the study to be performed without violating the methodology (neuropsychiatric disorders, including claustrophobia, severe pain syndrome, etc.).

Time limits for PET/CT with [¹⁸ F]-FDG after medical manipulations:

5-7 days after the biopsy;
12 days after completion of chemotherapy for hematological diseases;
14 days (ideally 21 days) after completion of chemotherapy for solid malignancies (with a shorter interval between injections - as close as possible to the next administration);
8 weeks (2 months) after the volumetric surgical intervention;
12 weeks (3 months) after completion of radiation therapy (radiation therapy of the brain is not a restriction to the study for all nosologies);
targeted, hormonal and immunotherapy does not affect the timing.

PET / CT is performed with intravenous administration of an iodine-containing radiopaque preparation in the absence of contraindications. It is necessary to provide the results of serum creatinine analysis (no more than 1 month old).
