Overview
PET CT combines positron emission tomography with CT for precise localization of metabolic activity. It is widely used in oncology cardiology and neurology. Hybrid imaging improves staging and therapy monitoring.
Tracer Handling
Radiotracer production logistics and timing are critical for PET studies. FDG is the most common tracer but many specialized tracers exist. Proper handling and quality control ensure reliable imaging.
Attenuation Correction
CT based attenuation correction improves PET quantification and image quality. Accurate registration between PET and CT is essential for interpretation. Motion management reduces misregistration artifacts.
Operational Considerations
Scanner calibration and daily QC maintain quantitative accuracy. Radiation safety protocols govern tracer handling and patient care. Scheduling accounts for tracer uptake times and scanner throughput.
