Dual Energy Computed Tomography Applications for the Evaluation of the Spine

Neuroimaging Clin N Am. 2017 Aug;27(3):483-487. doi: 10.1016/j.nic.2017.04.003.


Capturing the energy-dependent x-ray attenuation of different tissues, dual-energy computed tomography offers multiple benefits in the imaging of the spine, such as bone and iodinated contrast removal, monosodium urate imaging, and robust reduction of beam-hardening artifacts. The emerging new applications of this technique include bone marrow imaging in acute trauma and myeloinfiltrative disorders, improved bone density determination, and noninvasive assessment of spinal gout.
