Abstract

Computed tomography (CT) scans are an important radiologic modality for imaging the subaxial cervical spine. CT scans are now commonly used to screen patients and identify fractures in the subaxial cervical spine, rather than radiographic imaging. This chapter describes and illustrates subaxial cervical anatomy on CT imaging, with a focus on measures of spine relationships and CT-based landmarks for discs and joint spaces. In addition, CT findings in subaxial cervical spine trauma, injury types, and systems for scoring subaxial cervical trauma using CT imaging are discussed. Such scoring systems are becoming increasingly useful tools for triaging traumatic subaxial cervical injuries and can help in guiding patient management decisions, including the delivery of surgical versus nonsurgical treatments.
