Preparing the preparation:
- 3 ml of the eluate from the technetium-99m generator in aseptic conditions are injected with a syringe into a vial of lyophilizate, piercing the rubber stopper with a needle;
- It is forbidden to use an air needle;
- If necessary, dilute the eluate with an isotonic solution of sodium chloride before the required volume activity;
- the vial with the drug is placed in a lead container and heated in a water bath for 15 minutes from the boiling point of the water. The water level in the water bath should be higher than the level of the drug solution in the vial;
- the preparation is ready for use after cooling the contents of the vial to room temperature.
Introduce intravenously.
When examining patients to assess the blood supply of the myocardium at rest and under stress test conditions with an interval of about 24 hours, "Technetril, 99mTc "is administered in an amount of 259-370 MBq for each study on an empty stomach or at least 4 hours after ingestion.
After intravenous administration of the drug, a light breakfast (eggs, milk, tea, coffee) is recommended to the patient.
When visualizing malignant neoplasms, the drug is administered in an amount of 570-740 MBq for each study. After 20 minutes after the administration, planar (in three projections) or single-photon emission computed tomography is performed. When examining patients with suspected malignant neoplasm of the breast, they are placed lying on the stomach, with the breast mesh cut down, the detector is in the lateral position.
A ready-made preparation prepared on the basis of a lyophilizate contained in one vial can be used to study 5 patients.
