PET/CT is a unique quantitative imaging technique, but its quantitative power for clinical research can only become productive when there is strict standardization of imaging protocols. Additionally, a common quality control (QC)/quality assurance (QA) procedure must be in place to ensure that optimal quantitative images and data are acquired. The CTN has developed a Scanner Validation Program (.pdf) to establish baseline common quality control metrics for PET scanners used in multicenter studies. The ultimate goal is obtaining imaging consistency (standardization) across multiple centers in a single trial.
