Quantifying and Reducing the Effect of Calibration Error on Variability of PET/CT Standardized Uptake Value MeasurementsThe Journal of Nuclear Medicine | Feb 1, 2011(Free abstract. Full text $15)

Radiologists at the University of Washington in Seattle kept track of calibration factors for 2 PET/CT scanners for up to 3.5 years, and watched the incremental calibration error that accumulated despite regular manufacturer-recommended QA. Their article describes the steps they recommend to compensate forcalibration errors gradually introduced by "operator-influenced procedures."
