The development of PET/CT in determining gross tumor target volume of esophageal carcinoma in precise radiotherapy / 中华核医学与分子影像杂志

ABSTRACT

As the development of functional and molecular imaging,PET/CT gradually becomes one of methods in optimizing cancer radiotherapy treatment planning.Currently,numerous hospitals routinely use 18F-FDG PET/CT for the delineation of target volume in esophageal carcinoma (EC).However,the validity of 18F-FDG PET/CT in the delineation of target volume for EC is limited and needs further clinical validation.This review focuses on the value and validity of 18F-FDG PET/CT in the delineation of gross tumor target volume of EC primary lesions and regional lymph nodes.
