In recent years,the incidence rate of thymoma in China has been increasing gradually.Early preoperative accurate judgment of the risk classification of thymoma can affect the treatment plan and improve the clinical prognosis,as well as predict the risk of postoperative recurrence.The traditional imaging diagnosis is based on the morphological basis and the clinical experience of the diagnostician,and it is difficult to accurately distinguish tumor risk classification and cannot meet the standards of precision imaging medicine for biological individuals.Radiomics is the extraction of high-throughput characteristic spatial data information from medical images,and the construction of prediction models focusing on clinical problems,so as to noninvasively quantify tumor heterogeneity,aiming to tailor treatment plans according to the characteristics of individual patients and their tumors.This paper reviewed the research and application of radiomics in thymomas.
