Cervical spine trauma: evaluation by multidetector CT and three-dimensional volume rendering.

Multidetector-row computed tomography (CT) offers important advantages over conventional imaging modalities in the evaluation of the post-trauma cervical spine. It allows for faster scanning times, critical for triaging post-trauma patients as well as for eliminating motion artifacts, and allows for thinner collimation and the ability to achieve an isotropic data set which can be reformatted in any plane without loss of spatial resolution. In addition, three-dimensional volume-rendered reconstructions of images obtained using multidetector scanners can provide additional information in defining extent of injury, allowing neurosurgeons to see the fractures in any plane, simulating intraoperative views. 3D multidetector-row CT represents an advance in CT technology and can help ensure rapid, accurate evaluation of cervical spine injuries.
