PET影像组学在消化系统肿瘤诊疗中的研究进展

Research Progress of PET Radiomics in the Diagnosis and Treatment of Digestive System Tumors

影像组学采用医工相结合的方式,将传统图像转化为高维度、深层次的数字定量特征,挖掘图像的潜在生物标志物和异质性。消化系统恶性肿瘤在中国的发病率和死亡率均较高,近年来在人工智能发展和大数据时代的推动下,PET影像组学应用发展迅速,并在消化系统肿瘤的诊断、鉴别、疗效及预后评估等方面取得了一些有前景的研究成果,向无创性精确医学分析迈进。本文对PET影像组学在消化系统肿瘤中的诊疗进展进行综述,并分析面临的挑战与展望。

Radiomics adopts a combination of medical and industrial approaches to transform traditional images into high-dimensional and deep digital quantitative features,and to mine the potential biomarkers and heterogeneity of the images.Malignant tumors of the digestive system have high morbidity and mortality rates in China.In recent years,driven by the development of artificial intelligence and the era of big data,the application of PET radiomics has been developing rapidly and has achieved some promising research results in the diagnosis,differentiation,efficacy,and prognostic assessment of digestive tumors,and has progressed toward noninvasive precision medical analysis.This article reviews the progress of PET radiomics in the diagnosis and treatment of digestive system tumors,and analyzes the challenges and prospects.
