Abstract: Esophageal cancer which results in a relatively higher death rate is one of the most common cancers throughout the world. CT radiomics is a study to extract radiomics characteristics which are generalized from a large amount of CT images. These characteristics then underwent high-throughput quantitative analysis so that more heterogeneity information of the caner can be obtained. CT radiomics has been gradually used in forecast clinical stages and pathological differentiation of esophageal cancer in recent years, and applied in assessment of treatment effect and prognosis evaluation as well. This paper focuses on the application of CT radiomics in esophageal cancer and its progress.
