Abstract

Accurate measurements of electron density and effective atomic number are essential for precise imaging diagnosis and dose estimation in the multiparametric functional analysis of dual-energy computed tomography (CT). This paper provides a review of research progress pertaining to different dual-energy imaging modalities of CT for measuring electron density and effective atomic number accurately. Its aim is to offer a reference for improving the accuracy of imaging diagnosis and treatment planning.
