Dual-Energy Computed Tomography

**Semantic type:** Diagnostic Procedure

**Definition:** An application of computed tomography that uses different x-ray spectra to acquire two image sets at the same anatomic location. This technique allows for the analysis of energy-dependent changes in the attenuation of different materials and facilitates the differentiation, characterization, isolation, and distinction of the imaged tissue and material.

**Synonyms:** - DECT
