Abstract
With the progress of medical imaging technology and the accumulation of experience, dual-energy CT has moved from simple scientific research to clinical application. In the imaging of abdominal tumors, dual-energy CT has obvious advantages over conventional CT in improving the diagnostic performance, reflecting the pathological characteristics of malignant tumors and evaluating the therapeutic effect. This paper briefly describes the classification of dual-energy CT, the current research status of this technology in abdominal malignant tumors, and puts forward the challenges and application traps faced by dual-energy CT technology, in order to promote the clinical generalization and application of this technology.
