Posijet® Radiopharmaceutical fractionation and injection unit

The new Posijet® is the result of continuous improvement work to launch an automatic injector that meets the needs in radiation protection and efficiency during preparation and injection of FDG, FDopa, NaF, FCholine, but also 68Ga.

Posijet® offers unrivalled ease of use for the preparation and injection of high energy radiopharmaceuticals while guaranteeing the highest security conditions and radiation protection.

After 18 months, the new generation of Posijet® has been chosen by over 25 nuclear medicine departments and 300 users worldwide. After 5.535 mother solutions injected into 31.624 patients, Posijet® V3 satisfies users every day thanks to its reliability and ergonomics.

Radiation protection is optimized with a dose rate inferior to 15 μSv/h at 5 cm from the walls ( with a 37 GBq of FDG mother solution in its 30 mm lead shielded transport pot).

The Posijet®'s three main advantages

1. Posijet® minimizes operator’s exposure

  • Injection and rinsing operations in automatic and/or remote manual mode.
  • Reduction of potential distal doses, with the proposal of a wash out of the dose solution kit at the end of the cycle before unloading.

2. Easy to use and adapts to your work practices for maximum flexibility

  • Automatic mother solution volumic activity check and dilution assistant.
  • Consumables are 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 adjustable).
  • Possibility to reassign an already prepared dose.

3. Posijet® ensures the 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.
  • The secure integrated website allows remote control and monitoring of all operations carried out with Posijet®, accessible on PC and mobile devices (smartphone, tablet, etc.).

Paul Strickland Scanner Center, UK

More patients will soon be able to have a PET-CT scan at Paul Strickland Scanner Center on any given day, thanks to a new medical device.

The center is getting its first Posijet®, a machine that can safely administer most PET-CT tracers and free up valuable radiographer time, later this year. This will make the center only the second facility in England to have such a device. Paul Strickland Scanner Center installed the UK’s first clinical PET scanner in 1997.


University Hospitals Coventry and Warwickshire, UK

The nuclear medicine department of the University Hospitals Coventry and Warwickshire NHS Trust recently invested in a Lemer Pax Posijet. Matthew Galloway, principal clinical scientist, and his team have now been using the system for just over six months and it is already proving its worth.


Wales Research and Diagnostic PET Imaging Center, UK

After an unexpected audit where two members of the team had been exposed to doses of radiation that exceeded the maximum annual limit for Category B professionals, the Wales Research and Diagnostic PET Imaging Center (PETIC) in Cardiff decided to invest in an autoinjector for PET radiotracers to prevent overexposure to medical staff and patients.

Following a successful tender, the center chose the Posijet® because of its optimized technical performances, ergonomics, manoeuvrability, and safety for both patients and workers.
