Applications of 18F-FDG PET-CT for accurate radiotherapy of esophageal cancer / 国际肿瘤学杂志

ABSTRACT

Precise target delineation,target amendment and treatment plan regulation before radiotherapy and effect evaluation after radiothe-rapy are critical for the treatment of esophageal cancer.18F-fluorodeoxyglucose (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.
