Introduction
Quantitative PET imaging using standardized uptake values supports staging response assessment and therapy monitoring in oncology and other fields. Accurate quantification depends on consistent acquisition timing patient preparation and reconstruction parameters. Harmonization across centers is essential for multicenter trials and clinical comparability.
Acquisition and Reconstruction
Standardized uptake time tracer dose and reconstruction algorithms affect SUV measurements and must be controlled. Attenuation correction and motion management are critical for accurate quantification. Harmonized protocols and phantom based calibration improve cross site comparability.
Clinical Applications
Quantitative PET metrics guide therapy response assessment in oncology and support prognostic stratification in cardiology and neurology. Changes in SUV over time inform treatment efficacy and trial endpoints. Integration with CT or MRI morphological data enhances interpretation.
Quality and Standardization
Participation in accreditation programs and use of harmonization protocols reduce variability in quantitative PET. Documentation of acquisition parameters and reconstruction settings is necessary for reproducible results. Ongoing research refines quantitative biomarkers and thresholds for clinical decision making.
