Dual-Energy Computed Tomographic Applications for Differentiation of Intracranial Hemorrhage, Calcium, and Iodine

Ranliang Hu et al. Neuroimaging Clin N Am. 2017 Aug.

Abstract

This article reviews the physical principles of dual-energy material decomposition and its current implementation. Clinical applications of dual-energy material decomposition including differentiation of calcification from hemorrhage and iodinated contrast from hemorrhage are highlighted, and their applications to neuroimaging are reviewed.

Keywords: Calcification; Calcium overlay maps; Dual-energy CT; Intracranial hemorrhage; Iodine map; Iodine staining; Material decomposition; Virtual non-contrast images.
