摘要
随着三维适形和调强放疗技术的发展，放射治疗成为食管癌的重要治疗手段之一。准确的肿瘤分期和精确的靶区勾画是食管癌精确放疗成功的先决条件。常规影像在指导食管癌精确放疗计划、早期疗效监测以及检测肿瘤复发中有很大帮助，但仍存在许多局限性。PET／CT作为一种功能与解剖的融合影像，可以弥补传统影像的某些不足，在食管癌的诊治中发挥着越来越重要的作用。该文将主要对^18F—FDGPET／CT在食管癌放疗前分期、放疗靶区勾画、疗效监测及预后评估等方面的应用进行探讨。
With the development of three dimensional conformal radiotherapy and intensity modulated radiotherapy, radiotherapy becomes an important treatment for esophageal cancer. Accurate staging and target volume delineation are prerequisites for a successful treatment of esophageal cancer with radiotherapy. Conventional cross-sectional images are helpful for guiding radiotherapy plans, assessing treatment response and detecting recurrence. But there are still many limitations for anatomic information alone. PET/CT is an imaging fusion modality which may overcome some limitations of conventional cross- sectional modalities. It plays an important role in the diagnosis and treatment of esophageal cancer. This review evaluates the applications of 18^SF-FDG PET/CT in the initial staging before radiotherapy, its target volume definition, treatment response and the prognosis of esophageal cancer.
