Utilization of positron emission tomography (PET) for radiotherapy

Abstract

Positron emission tomography (PET) can obtain functional information about tumors. There are some reports that intensity modulated radiation therapy (IMRT) planning was made using hypoxic imaging information obtained by PET. We used a semiconductor PET which was developed by the Department of Nuclear Medicine in Hokkaido University, where hypoxic imaging by [18F] fluoromisonidazole (FMISO) PET is available. We are investigating a dose escalation planning study of IMRT using FMISO PET imaging, and report on the usage of PET for radiotherapy in Hokkaido University.
