摘要
放疗前对靶区进行精确勾画、修正靶区和调节治疗计划，放疗后评价疗效对食管癌的治疗至关重要。^18F-氟脱氧葡萄糖（^18F-FDG）正电子发射计算机断层显像（PET）-CT将PET功能影像和CT解剖影像有机结合，为PET提供更多的解剖细节，并且可从分子水平反映肿瘤组织和正常组织的生化变化和代谢状态之间的差异，为食管癌的治疗提供更多有价值的帮助。
Precise target delineation, target amendment and treatment plan regulation before radiothe- rapy and effect evaluation after radiothe-rapy are critical for the treatment of esophageal cancer. ^18F-fluorode- oxyglucose （FDG） positron emission tomography （PET）/CT, a unique combination of the functionally metabolic PET imaging and the anatomical CT imaging, can provide more anatomical details for PET, and it can reflect differences in tumor and normal tissue metabolic states and biochemical changes at the molecular level, and provide more valuable assistance for the treatment of esophageal cancer.
