摘要

Objective. - We compared two reconstruction methods for 18fiuorodeoxyglucose (F-18-FDG) positron emission tomography (PET) images with "attenuation weighted ordered subset expectation maximization" using either the manufacturer-provided (AW-OSEM) or a "Detector response" (AW-OSEM DR) tomographic operator. We looked at the feasibility of using the latter reconstruction for radiotherapy target volumes definition in cancers of the superior aero-digestive tract (VADS). In this preliminary study, we first assessed the spatial resolution of images obtained with AW-OSEM and AW-OSEM DR on a Biograph (TM) 6, and secondly target volumes of radiotherapy "Gross Tumor Volume" (GTV), "Clinical Target Volume" (CTV) and "Planning Target Volume" (PTV) obtained with each of these reconstruction methods.
