Multienergy Computed Tomography Applications: Trauma

Radiol Clin North Am. 2023 Jan;61(1):23-35. doi: 10.1016/j.rcl.2022.07.003. Epub 2022 Oct 10.


Computed tomography (CT) plays an important role in trauma because imaging findings directly impact management. Advances in CT technology, specifically multienergy CT, have allowed for simultaneous acquisition of images at low and high kilovolt peaks. This technique allows for differentiation of materials given that materials have different absorption behaviors. Various multienergy CT postprocessing applications are helpful in the setting of trauma, including bone subtraction, virtual monoenergetic imaging, iodine-selective imaging, and virtual noncontrast imaging. These techniques have been applied from head to toe and have been used to improve image quality and increase conspicuity of injuries, which increases diagnostic confidence.
