Radiomics is an emerging data transformation method for images,which provides theoretical basis for the analysis of heterogeneity before and after ablation of tumors such as lung cancer,liver cancer,etc.,based on which a model system for assessing the efficacy and prognosis of tumors after ablation can be constructed,and it can be used to guide the later treatment and adjust the plan in a real-time,precise,and objective way.Through the calibration and verification of a big data,this technology is becoming more and more mature and stable,and has now become a hotspot of research.This paper aims to make a brief review about the application value of radiomics features and the utilization of the relevant models in evaluating the efficacy and in predicting the prognosis after ablation treatment of tumors.(J Intervent Radiol,2024,33:693-696)
