  1. FDG-PET/CT Technical Committee Purpose: • to foster adoption of practical [I deleted cost-effective because I do not see us doing any cost-effective analyses. Those are very complex] standards for accurate and reproducible quantification of tumor metabolism via serial measurements from FDG-PET/CT. Objectives •    Identify clinically significant covariates in the quantification of FDG signal and recommend recording and normalization standards. •   Compare the various vendors’ computations for quantification and make recommendations to ensure any patient’s images would yield the same numbers irrespective of vendor. •    Define the parameters for automated setting of regions of interest. •    Develop a Digital Reference Object (image database) for quality control •   Enable tracking of software versions.

  2. FDG-PET/CT Technical CommitteeAchievements and Next Steps The Digital Reference Standard subcommittee has • acquired images of a single reference phantom from multiple vendors’ scanners, • compared the DICOM header information, • harmonized the standard with the AAPM/SNM Task Group 146. Next steps • establish a procedure for distributing and beta-testing a digital image set, • test on third-party review stations • initiate the QIBA process for dissemination.
