Phantom Updates for ACR Nuclear Medicine and PET Accreditation

ACR Nuclear Medicine Accreditation

Effective Jan. 1, 2024, the definition of a small rectangular field camera for nuclear medicine phantoms will change to the smallest dimension < 32 cm (current requirement is the longest dimension < 32 cm). The purpose of this update is to better identify scanners with a small field of view (FOV) and differentiate the small FOV scanners from those with a large FOV.

Please refer to the Phantom Testing: Nuclear Medicine article for details. Be sure to carefully review the requirements before submitting testing items for accreditation review. Requirements are subject to change at any time. Please check ACR requirements frequently for updates.

If you have questions, please submit a support ticket. Select "Accreditation" for Support Team and "Ultrasound/NM/PET Technical" for Category.

ACR PET Accreditation

Effective Jan. 1, 2024, the mean background criteria for PET phantoms will change to 0.90-1.10 for SUV measurements. The aim for this update is to reduce the variability tolerance of the background SUV to +/- 10% from the previous +/- 15%. This change helps to improve the accuracy of scanner calibration and SUV measurements.

Please refer to the Phantom Criteria and Phantom Testing: PET articles for details. Be sure to carefully review the requirements before submitting testing items for accreditation review. Requirements are subject to change at any time. Please check ACR requirements frequently for updates.
