Miscellaneous and Emerging Applications of Dual-Energy Computed Tomography for the Evaluation of Pathologies in the Head and Neck

Neuroimaging Clin N Am. 2017 Aug;27(3):469-482. doi: 10.1016/j.nic.2017.04.008. Epub 2017 Jun 7.


Dual-energy computed tomography (DECT) and its specific algorithms and applications have been increasingly recognized in clinical practice as a valuable advance in technology beyond what is possible with the established postprocessing capabilities of single-energy multidetector computed tomography, mainly because of its potential benefits regarding image quality and contrast. DECT may represent an alternative approach to purely attenuation-based imaging of the head and neck, because it provides a material-specific visualization based on spectral information. With this approach, owing to its physical properties, iodine can be assessed as a potential "biological tracer" to improve depiction of tumor conspicuity and grade of invasion.
