New: Consensus Recommendation for PET/MRI in Oncology

August 28, 2023

A consensus recommendation for the use of positron emission tomography/magnetic resonance imaging (PET/MRI) in oncologic imaging in adults has been released by the SNMMI, the European Association of Nuclear Medicine (EANM) and the International Society for Magnetic Resonance in Medicine (ISMRM).

The objective of the new recommendation is to share basic technical acquisition groundwork and to provide a minimum agreeable standard imaging protocol for the main PET/MRI indications in oncology. Rather than providing fixed recommendations, the guideline suggests where PET/MRI should be used instead of PET/CT or MRI+PET/CT.

“The purpose of this guideline is also to provide PET/MRI users with a common denominator for recommending, performing, interpreting, and reporting the results of the most used PET/MRI indications,” the authors said. It is meant to “describe the technological possibilities and how to properly adapt the combined acquisition techniques according to clinical indications.”

The recommendation covers PET/MRI technology fundamentals, quality controls, qualifications and responsibilities of personnel, quality assurance/control of PET and MRI, procedures/specifications for the examination, and PET/MRI protocols based on clinical indications. It also includes discussion of image interpretation, quantification, and reporting.
