Features and Prospects of Dual-energy Computed Tomography for Evaluation of Lung Cancer / 中国医学科学院学报

ABSTRACT

Dual-energy computed tomography,with fast image acquisition at two different X-ray energies,enables material-specific and spectral imaging,which offers objective and quantitative parameters for tumor detection,characterization,staging,and treatment monitoring without increasing radiation exposure.This article reviews the applications of dual-energy computed tomography technique and its applications in the evaluation of lung cancer and elucidates its future developments.
