Abstract
En 中文
Previously published effective dose coefficient estimates for 15O-water are around 1 μSv/MBq, resulting in an effective dose of around 0.4 mSv for a typically injected activity of 400 MBq in clinical cardiac scans. These estimates were based on limited PET information combined with pharmacokinetic models. Large axial field of view (LAFOV) PET allows for dynamic scanning of all relevant organs in a single scan and hence should result in more accurate dosimetry estimates. The aim of the present work was to estimate radiation dosimetry of 15O-water based on dynamic LAFOV PET.
