摘要目的评估双期18F-FDG PET/CT预测骨肉瘤新辅助化疗(NAC)后组织学反应的能力。方法回顾性分析31例经新辅助化疗及手术治疗的骨肉瘤病人资料。经注射18FFDG,于新辅助化疗前后采集早期(60 min)及延迟期(150 min)PET信息。测量肿瘤新辅助化疗前后的SUV最大值(SUVmax),早期/延迟期SUV最大值变化(RImax)及早期/延迟
Abstract Objective To evaluate the ability of dual-phase 18F-FDG PET / CT in predicting the histological response to neoadjuvant chemotherapy (NAC) in osteosarcoma. Methods A retrospective analysis of 31 cases of neoadjuvant chemotherapy and surgical treatment of osteosarcoma patients. After injection of 18FFDG, PET information was collected before and after neoadjuvant chemotherapy (60 min) and delayed (150 min). The maximum SUV (SUVmax) before and after neoadjuvant chemotherapy, RImax and early / late
