Image quality and variability for routine diagnostic FDG-PET scans in a Japanese community hospital: current status and possibility of improvement

摘要

In Japan, commercially delivered FDG is manufactured in three batches per day at fixed constant activity and distributed in vials. Consequently, the amount of activity administered to the patient varies depending on the timing of injection. We evaluated a method for adjusting the scan time according to the body mass index (BMI) to obtain equivalent image quality for every patient.
