Pharmacodynamics:

Normally, with the introduction of this RFP, the following organs are visualized in order of decreasing accumulation level: cerebral cortex, myocardium, renal pelvis and bladder, oropharynx, stomach.RFP can accumulate in the colon, muscles of skeletal musculature, areas of brown fat accumulation. In other organs and tissues, the background accumulation of RFP is normal. Hyperfixation of RFP is observed in the cerebral cortex and myocardium as a result of an increased level of glucose metabolism in these organs. "Fluodeoxyglucose, 18?" Is a nonspecific tumorotropic radiopharmaceutical and accumulates in increased amounts in malignant tumor cells and metastases, which is due to the inherent hyperglycolysis. The degree of accumulation of fluorodeoxyglucose, 18P in the cells of malignant tumors correlates with the degree of their malignancy. The drug also allows you to evaluate the effect of the treatment, because with effective treatment, the level of accumulation of the drug in tumors decreases, and when ineffective - does not change or increases. F-dedeoxyglucose, F is actively transported into cells by transporter proteins, where it is phosphorylated to produce fluorodeoxyglucose-6-phosphate, 18F, a product that does not enter into further reactions, and is thus retained in malignant tumor cells.In unaltered cells of tissues and organs dephosphorylation is observed with the formation of fluorodeoxyglucose, 18F, which is excreted from normal cells and can be redistributed. The best conditions for the detection of malignant tumors are created with mild hypoglycemia, achieved by fasting for 4-6 hours, and by a water load (intake of 500-800 ml of water) after the administration of RFP. The patient is offered several times to empty the bladder. Fasting promotes increased uptake of glucose by cells, and the water load accelerates the removal of a label from normal tissues with urine, as a result of which the level of radioactive background and radiation load decrease. In patients with diabetes, blood glucose should be monitored prior to testing. PET-examination is carried out only under condition of normal or low blood glucose level.

"Fluodeoxyglucose, 18P" is a cardiotropic RFP, and in its diagnostic properties is suitable for the study of glucose metabolism in the myocardium. RFP allows to assess the degree of viability of the myocardium in planning reconstructive operations in patients with coronary heart disease andsystolic dysfunction of the left ventricle, to monitor the effectiveness of myocardial treatment.

Pharmacokinetics:

After intravenous injection of fluorodeoxyglucose, 18P quickly leaves the bloodstream and gradually accumulates in organs and tissues. From the body ftorodezok-siglukoza, 18P is excreted through the kidneys into the bladder, so the kidneys, ureters and bladder are also visualized in the norm. More than 50% of the administered amount of RFP is excreted from the body with urine in the first 2 hours after the injection. In the brain, increased accumulation of RFP is observed in the cortex and deep structures, and the content of RFP in gray matter is 2 times higher than in white matter. Accumulation of the drug in the human myocardium is 3-4% of the injected. The optimal body / background ratio for myocardial and brain examinations is reached 35-40 minutes after intravenous administration of the drug and remains for another 25-30 minutes, which is sufficient for conducting positron emission tomography. The optimal tumor / normal tissue ratio is observed 45-120 minutes after drug administration, and remains for 240-360 minutes after administration.

Indications:

RFP "Fluodeoxy glucose, 18F" is used as a diagnostic tool for positron emission tomography (PET). The main indications for the study are:

in oncology:
differential diagnostics of malignant tumors of various nosological forms and localization, including neoplasms of the brain, determination of the prevalence and staging of malignant neoplasms, evaluation of the effectiveness of tumor treatment;
in cardiology:
assessment of myocardial viability in the planning of reconstructive surgeries in patients with coronary heart disease and left ventricular systolic dysfunction, monitoring the effectiveness of myocardial treatment;
in neurology:
identification of foci of hypometabolism in epilepsy, differential diagnosis of parkinsonism, determination of the degree of brain damage in cases of craniocerebral trauma and cerebrovascular diseases, determination of the effectiveness of treatment of neurological and psychoneurological pathology.

Contraindications:

Specific contraindications to the use of the drug is not found. The use of RFP "fluorodeoxyglucose, 18F" is contraindicated in pregnancy and lactation.

Dosing and Administration:

"Fluodeoxyglucose, 18F" in the form of a sterile solution is injected intravenously.

From the pharmacokinetic data on the time of maximum accumulation of fluorodezox-siglucose, 18F in the organs and the rate of its removal, it follows that the optimal time for the onset of myocardial and brain scans is 35-40 minutes after drug administration, while the conditions for the study of the brain and myocardium persist within 60-70 minutes after its administration.

In the "whole body" study, the optimal time to start scanning is 90-120 minutes after intravenous RFP. Optimal conditions for the study of the whole body in cancer patients are preserved within 4 hours after the administration of RFP.

The diagnostic dose of RFP for conducting positron emission tomography of the brain and myocardium is 100-120 MBq per 1 m2 of the body surface of the patient, with a typical use of 150-240 MBq per study. The surface of the body is calculated from the nomogram based on the weight and height of the patient. The drug is injected intravenously in a volume of 0.5-2.0 ml.

With a PET whole-body examination, the diagnostic dose of the drug is 220 MBq per 1 m2 of the body surface of the patient; as a rule, use 300-550 MBq per study.The drug is administered intravenously slowly in a volume of 5.0-10.0 ml. Usually, before administration, the dose of "Fluodeoxyglucose, 18F" required for a given patient is diluted with sterile saline, bringing the contents of the syringe to 5.0-10.0 ml, which is necessary to accurately dose the injected activity and reduce RFP uptake in the brain and myocardium. The radioactivity of the drug remaining in the syringe after the administration should be measured to clarify the dose administered.
