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.
