Posijet® offers an unrivaled ease-of-use  for preparation and injection of high energy radiopharmaceuticals while guaranteeing highest security conditions and radiation protection for both the user and the patient while guaranteeing the integrity of the radioactive drug.

Posijet® collects, measures and injects the required patient dose in maximum safety and reliability conditions

This compact, self-contained, radiation protected radiopharmaceutical fractionating and injection unit supports all multi-dose fluorinated tracers (18F) including 18F-FDG, 18F-DOPA, 18F-CHOLINE, 18F-FNA, 18F-PSMA … and also tracers labelled with 68Ga, as well as Ammonia labelled with 13N for cardiac PET examinations.

With its new “Therapy” application, it is also able to perform slow administrations in 30 minutes, for Vectorised Internal Radiation Therapy (VIR) treatments. Especially with 177Lu labelled radiopharmaceuticals (177Lu octreotate or 177Lu DOTA-TATE, 177Lu-PSMA-617 …). It is also possible to perform fractionating and intravenous administration of 99mTc-labelled SPECT radiopharmaceuticals.
For routine diagnostic applications, Posijet® features a very fine sampling capacity of 100 μL of the stock solution with an average dose preparation time of 50 seconds and an accuracy of around 2 %. The average injection time, including rinsing operations, is less than 1 minute 30 seconds.

Making it the most versatile shielded preparation and injection unit currently available on the market.

Designed to reduce operator’s exposure to its minimum:

  • Injection and rinsing operations in automatic and/or remote manual mode.
  • Wash out of the dose solution kit at the end of the cycle before unloading.
  • Radiation protection guarantees a dose rate of less than 25 μSv/h
  • Real-time update of the stock solution information for permanent follow-up and control of the users.

Posijet® is very easy to use and adapts to your work practices for maximum flexibility:

  • Automatic mother solution volumic activity check and dilution assistant.
  • Consumables quick and easy to install.
  • Intuitive, user-friendly interface.
  • “Test injection site” function before the administration of the radiopharmaceutical by bolus NaCl (the volume of the bolus is ajustable).
  • Possibility to reassign an already prepared dose.

Last, Posijet® ensures highest safety conditions for patient and operator:

  • Maximum dose threshold, air bubble detector, injection force sensor.
  • Interoperability with all WIFI and ethernet connected radiopharmacy software.
  • Secure integrated web site allows remote control and monitoring of all operations carried out with Posijet®
  • Three injection profiles to prevent the risk of extravasation.

Mainly indicated for cardiac PET diagnostic imaging, this new specific application makes Posijet® the first preparatory injection unit capable of handling 13N. Despite an extremely short half-life (10 minutes), Posijet® accurately prepares the patient dose and administers it according to the strict protocol required for the success of this specific PET examination. Exchanges between the Geneva University Hospitals (HUG) and the Lemer Pax development teams have enabled the routine use of 13N-Ammonia dose preparations with Posijet® since 2019.

The hospital currently performs approximately 1 600 examinations per year, while ensuring a considerable reduction in exposure for medical staff.
