Disease localization isolated to the apex has not been established.
Cardiac imaging should be done 10 minutes following the administration of sodium pertechnetate Tc 99m (in vivo method) or Tc 99m labeled red blood cells (modified in vivo/in vitro method) utilizing a scintillation camera interfaced to an electrocardiographic gating device. In comparison with most other diagnostic technetium labeled radiopharmaceuticals, the radiation dose to the ovaries (1.5 rads/30 mCi at rest, 1.2 rads/30 mCi at exercise) is high. The breast should not be compressed on the overlay. The pH of the reconstituted drug is between 4.5 and 7.5.

* Percentage of procedures in which at least one lymph node contained the specific tracer; the percents do not add to 100% due to rounding.

Method of Calculation: The following radiation absorbed dose values were obtained using the Medical Internal Radiation Dose Committee (MIRD) Schema.

In studying patients in whom cardiac disease is known or suspected, care should be taken to assure continuous monitoring and treatment in accordance with safe, accepted clinical procedure. Out of 72 patients who had both evaluable Technetium TC 99M Sestamibi scans and evaluable angiographic images, only one patient had both an abnormal angiogram and an abnormal Technetium TC 99M Sestamibi scan. These lesions were identified in sites that did not physically correlate with identified entry criteria mammographic lesions and these lesions were not palpable. Also, before administering Technetium TC 99M Sestamibi Injection, patients should be asked about the possibility of allergic reactions to the drug. No clinically meaningful measurements of sensitivity, specificity or other diagnostic performance parameters could be demonstrated in this study.

Cardinal Health 414, LLC's Kit for the Preparation of Technetium TC 99M Sestamibi Injection is not to be used with the Recon-o-Stat™ thermal cycler due to the smaller vial size requirements of this heating device. Technescan™ PYP™ (Kit for the Preparation of Technetium Tc 99m Pyrophosphate Injection) is a sterile, non-pyrogenic, diagnostic radiopharmaceutical suitable for intravenous administration after reconstitution with sterile sodium pertechnetate Tc 99m injection or sterile 0.9% sodium chloride injection. There have been no studies in pregnant women. Discard unused drug after 6 hours from the time of formulation. A study in a dog myocardial ischemia model reported that Technetium TC 99M Sestamibi undergoes myocardial distribution (redistribution), although more slowly and less completely than thallous chloride Tl-201. optimal hydration; remove metal objects Note 3: Keep the Radioactive Preparation in the lead shield described below (with cap in place) during the useful life of the Radioactive Preparation.

Usual Dosage: See complete prescribing information. An initial marker image, that was not used in the data analysis, was obtained using a cobalt Co57 point source as a marker of a palpable mass. No bacteriostatic preservative is present. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Technetium TC 99M Sulfur Colloid Injection and any potential adverse effects on the breastfed child from Technetium TC 99M Sulfur Colloid Injection or from the underlying maternal condition. The reports were insufficient to establish the basis for failed tracer localization. Anticoagulation of the blood is provided by residual heparin in the intravenous line. For the anterior image, the patients were supine.

Toxicology data are available upon request. No genotoxic activity was observed in the Ames, CHO/HPRT and sister chromatid exchange tests (all in vitro). Each 10 milliliter reaction vial contains 11.9 milligrams sodium pyrophosphate, 3.2 milligrams (minimum) stannous chloride (SnCl2•2H2O) and 4.4 milligrams (maximum) total tin expressed as stannous chloride (SnCl2•2H2O) in lyophilized form under an atmosphere of nitrogen.

Technetium Tc 99m Sestamibi should be given to a pregnant woman only if clearly needed. Limited available data with Technetium TC 99M Sulfur Colloid Injection use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes; technetium Tc 99m crosses the placenta (see Data). glucagon, GlucaGen, Ceretec, mannitol, Aridol.

Specific drug-drug interactions have not been studied. The stopcock is then turned, residual blood is flushed from the intravenous line, and the normal saline flow is readjusted. If not, the reaction vial should not be used.

Technetium Tc 99m Pertechnetate is excreted in human milk during lactation. Parenteral drug products should be visually inspected for particulate matter and discoloration prior to administration whenever solution and container permit. The random effect meta-analytical methods take into account the sample size of each study as well as within and between study variability. Preparation of the Technetium TC 99M Sestamibi from the Kit for Preparation of Technetium Tc 99m Sestamibi Injection is done by the following aseptic procedure: Note: Adherence to the above product reconstitution instructions is recommended. In some patients the allergic symptoms developed on the second injection during Tc 99m Sestamibi imaging. Hence, Sodium Pertechnetate Tc 99m Injection containing oxidants should not be used. discard after six (6) hours from the time of preparation. Non-Palpable Mass and an In patients with documented myocardial infarction, imaging revealed the infarct up to four hours post dose. Prior to lyophilization the pH is adjusted with hydrochloric acid. The contents are sealed under nitrogen. However, after the Sodium Pertechnetate Tc 99m Injection is added, adequate shielding of the final preparation must be maintained.
