Factors affecting SUV

Technical factors • scan acquisition parameters • image reconstruction settings • region of interest strategies • SUV calculation/normalization • use of blood glucose level correction • use of contrast agents

Biological factors • blood glucose level

• patient motion • patient comfort • Inflammation

Errors • cross-calibration PET versus dose calibrator • rest/remaining activities in syringe • incorrect synchronization of clocks • use of injection time rather than dose calibration time • paravenous injection
