{{Neck trauma - indication for imaging}}
{{Neck trauma - choice of modality}}
==Evaluation==
*Incongruences?
*Prevertebral thickening? <ref name="prevertebral" group="notes">In contrast, [[CT of the neck in trauma]] has a higher sensitivity in directly visualizing skeletal injuries, making it optional to evaluate the indirect sign of prevertebral thickening. Hence, the threshold for prevertebral thickening is higher when evaluating CTs. {{Further|CT of the neck in trauma}}</ref>
*Any fracture lines?
===Incongruencies===
Lines drawn along the anterior and posterior surfaces of vertebrae as well as the spinous processes should be smooth.
Also, the distances between vertebrae and spinous processes should be compared.
===Prevertebral thickening===
Upper limits of values vary with body constitution of the patient, but are generally as follows:
*Children: Less than 6 mm at the level of C3<ref name="DebnamGuha-Thakurta2012">{{cite journal|last1=Debnam|first1=J. Matthew|last2=Guha-Thakurta|first2=Nandita|title=Retropharyngeal and Prevertebral Spaces|journal=Otolaryngologic Clinics of North America|volume=45|issue=6|year=2012|pages=1293–1310|issn=00306665|doi=10.1016/j.otc.2012.08.004}}</ref>
*Adults: Less than 6 mm at C2 and less than 22 mm at C6<ref name="DebnamGuha-Thakurta2012"/>
Thresholds are higher on CT.<ref name="prevertebral" group="notes"/>
==Report==
Even absence of:
*Fracture
*Misalignment
*Prevertebral thickening
