Tc 99m: The Core of Nuclear Medicine Imaging1,2

TechneLite® is a self-contained technetium-99m (Tc-99m) generator that provides the essential medical isotope used by hospitals and radiopharmacies to radiolabel Cardiolite® (Kit forTechneLite Generator the Preparation of Technetium Tc99m Sestamibi for Injection), NEUROLITE® (Kit for the Preparation of Technetium Tc99m Bicisate for Injection), and other radiopharmaceuticals requiring Tc-99m used in nuclear medicine imaging procedures.

With over 50 years of TechneLite® generator manufacturing experience and expertise, we are a proven and reliable supplier of technetium-99m for the radiopharmacies, hospitals and patients we serve.3

The TechneLite® generator is a source of sodium pertechnetate Tc 99m for use in the preparation of FDA-approved diagnostic radiopharmaceuticals, as described in the labeling of these diagnostic radiopharmaceutical kits.

Sodium Pertechnetate Tc 99m Injection is used IN ADULTS as an agent for:

Sodium Pertechnetate Tc 99m Injection is used IN CHILDREN as an agent for:


None known.


Allergic reactions including anaphylaxis have been reported infrequently following the administration of Sodium Pertechnetate Tc 99m Injection.


Radiation risks associated with the use of Sodium Pertechnetate Tc 99m Injection are greater in children than in adults and, in general, the younger the child, the greater the risk owing to greater absorbed radiation doses and longer life expectancy.
These greater risks should be taken firmly into account in all benefit-risk assessments involving children.  Long-term cumulative radiation exposure may be associated with an increased risk of cancer.


Since the eluate does not contain an antimicrobial agent, it should not be used after 12 hours from the time of TechneLite®, Technetium Tc 99m Generator, elution. After the termination of the nasolacrimal imaging procedure, blowing the nose and washing the eyes with sterile distilled water or an isotonic sodium chloride solution will further minimize the radiation dose. As in the use of any radioactive material, care should be taken to minimize radiation exposure to patients and occupational workers. Radiopharmaceuticals should be used only by physicians who are qualified by training and experience and who are licensed in the safe handling of radionuclides.
