Dual Energy Computed Tomography in Head and Neck Imaging: Pushing the Envelope

Neuroimaging Clin N Am. 2020 Aug;30(3):311-323. doi: 10.1016/j.nic.2020.04.003. Epub 2020 Jun 10.

Abstract

Multiple applications of dual energy computed tomography (DECT) have been described for the evaluation of disorders in the head and neck, especially in oncology. We review the body of evidence suggesting advantages of DECT for the evaluation of the neck compared with conventional single energy computed tomography scans, but the full potential of DECT is still to be realized. There is early evidence suggesting significant advantages of DECT for the extraction of quantitative biomarkers using radiomics and machine learning, representing a new horizon that may enable this technology to reach its full potential.
