Three nuclear medicine organizations have jointly endorsed a unified PET/CT and PET/MRI scanner accreditation framework to standardize quantitative PET imaging worldwide.
The Society of Nuclear Medicine and Molecular Imaging Clinical Trials Network (SNMMI-CTN), the Australasian Radiopharmaceutical Trials Network (ARTnet), and the European Association of Nuclear Medicine (EANM) Forschungs GmbH signed the memorandum of understanding on October 6, with full transition to CRC-based accreditation to be completed in January 2026.
“Through this collaboration, SNMMI, ARTnet, and EANM are laying the groundwork for a future where data from any accredited scanner, anywhere in the world, can be trusted and compared with confidence,” the SNMMI said in a December 16 statement.
Currently, PET system accreditation methods, along with the associated phantoms and acceptance criteria, vary widely across clinical research organizations (CROs), sponsors, and professional networks. This lack of harmonization results in duplicative testing, unclear responsibilities, increased costs, and inconsistent quantitative data, the SNMMI noted.
The new framework directly addresses these inefficiencies by introducing a contrast recovery coefficient-based accreditation system to replace the current SUV recovery coefficient-based methods, the SNMMI noted.
