Assessment of tumour size in PET/CT lung cancer studies: PET- and CT-based methods compared to pathology

摘要

BackgroundPositron emission tomography (PET) may be useful for defining the gross tumour volume for radiation treatment planning and for response monitoring of non-small cell lung cancer (NSCLC) patients. The purpose of this study was to compare tumour sizes obtained from CT- and various more commonly available PET-based tumour delineation methods to pathology findings.
