Accreditation specifications

New EANM FDG PET/CT accrediation specifcations for SUV recovery coefficients

 

EARL is dedicated towards improving and supporting the quality of nuclear medicine procedures. The EARL accreditation is based on quality control (QC) experiments that were described and published in the EANM guidelines in 2010. Meanwhile the field has moved forward and new developments, technologies and insights have become available. Therefore EARL contacted all EARL accredited centres of excellence in August 2013 in order to kindly request some additional measurements regarding PET/CT (SUVpeak, PSF reconstruction) since EARL would like to adapt and further improve the accreditation programme such that new scanner technologies and data analysis procedures can be accommodated. As soon as some results are available, EARL will inform all sites, which are participating in the EARL accreditation programme, and will also publish the results on the EARL website.

Meanwhile the following specifications are valid:

Based on the results observed during the first pilot study on the accreditation of PET/CT systems as described in the EANM guideline for quantitative FDG PET/CT studies, a redefinition (improvement) of the SUV recoveries seems feasible and warranted.
