Abstract

Two treatment planning methods for nasopharyngeal carcinoma were compared: conventional whole-body BGO scintillator positron emission tomography and a new brain PET system using semiconductor detec- tors. The average absolute volume of GTV contoured with the use of the new brain PET system was significantly smaller than that of conven- tional whole-body BGO PET. The new brain PET system using semiconductor detectors can provide more accurate tumor delineation
