Report No. 126 - PET/CT Acceptance Testing and Quality Assurance (2019)

Category: Reports

A rigorous and ongoing quality assurance (QA) program for dual-modality positron emission tomography/computed tomography (PET/CT) systems is recommended to include an initial evaluation of scanner performance to establish a baseline of measurements and then periodic assessment of system performance of the scanners on an annual, semi-annual, quarterly, weekly, and daily basis. Over the years, numerous agencies have published their recommendations for such an assessment, including the Society of Nuclear Medicine and Molecular Imaging (SNMMI), International Electrotechnical Commission (IEC), International Atomic Energy Agency (IAEA), American College of Radiology (ACR), and National Electrical Manufacturers Association (NEMA) [1–9]. Since the early 1990s, the most widely implemented and cited reference for testing these systems has been the NEMA Standards Publication NU 2–Standard Performance Measurements of Positron Emission Tomographs (PET) set forth by the Medical Imaging and Technology Alliance (MITA) division of NEMA. However, the NEMA NU 2 and other standards can be challenging to follow given their requirements for specialized software, equipment, and phantoms [10].
