Abstract： Radiomics is an emerging tumor diagnosis and auxiliary detection technique that has undergone rapid development in the past few decades. The availability of new imaging equipment and reagents, as well as the use of standardized imaging protocol, has made quantitative and standardized imaging analysis possible. Radiomics is a field of study that involves the extraction of a large number of quantitative features from areas of interest in medical images using data-characterization algorithms, and transformation of these data into first-order or high-order data. The accuracy of clinical diagnosis and prognostic value of radiomics can be further improved by analyzing the relationship between data layers. Although radiomics has many advantages and has made great progress, its standardization, reliability, and application in large data and multicenter studies will need to be further optimized.
