Overview
PET CT combines metabolic PET imaging with diagnostic CT for lesion localization staging and therapy response evaluation.
Patient Preparation
Fasting glucose control and tracer specific uptake time protocols are essential for reproducible quantitative imaging.
Acquisition and Reconstruction
Include low dose CT for attenuation correction and diagnostic CT with contrast when indicated; use standardized uptake value quantification and harmonized reconstruction.
Reporting and Follow Up
Document tracer uptake patterns SUV metrics and correlate with CT morphology for staging and treatment monitoring.
