中文摘要：

影像组学是精准医疗的重要组成部分，也是医学影像学发展的必然趋势。近年来，其在疾病诊疗上的应用得到越来越多学者和临床工作者的关注和研究。目前，各研究者所用的影像组学方法不一，扫描参数及分析方法尚未形成标准化，对各系统疾病的研究进展存在较大差异，研究结果可重复性也有待进一步验证。本文就影像组学在消化道肿瘤（食管癌、肝癌、结直肠癌）诊断、治疗、疗效及预后评价等方面的研究应用进行综述。

英文摘要：

adiomics is an important part of precision medicine, which is also an inevitable trend of the development of medical imaging. In recent years, the application of radiomics in the diagnosis and treatment of disease has been paid more and more attention by scholars and clinical workers. However, the radiomics study methods, scanning parameters and analysis methods have not been standardized and the repeatability of research results needs to be validated. In addition, there is a big difference between the research progress of the disease. This article is to review the research and application of imaging in the diagnosis, treatment, curative effect and prognosis of digestive system neoplasms（esophageal cancer, liver cancer, colorectal cancer）.
