摘要 肿瘤放射治疗已进入PET及PET—CT引导的生物适形治疗时代,PET及PET—CT改进和优化了综合治疗计划的实施,改进了放疗计划的实施目的,精确了肿瘤放疗靶区的制定,同时在靶区勾画过程中大大减少了不同医生所勾画靶区的差异,并减少了勾画靶区的偏倚,通过准确靶区范围而使治疗-效益比提高。 Oncology radiotherapy has entered into the biologic eonformal radiotherapy era which is guided by PET and PET-CT. PET and PET-CT can change and improve oncology integration therapy plan and the aim of radiotherapy plan, can make radiotherapy target volume more exact and reduce the observer variation in drawing the target volume, which can reduce target volume bias. More exact target volume leads to higher therapy-effect.
