The purpose of the study was to determine the time needed to perform a helical CT examination of the entire cervical spine. Our study population included 156 trauma victims: 100 of these patients underwent CT examination in conjunction with a cranial examination; the remaining 56 patients underwent a primary cervical examination only.
Performing a cervical CT examination in conjunction with a cranial CT examination added an average of 12 min to the overall study time. The time for performing a primary cervical examination was 11 min on average. These times are approximately half of those required for a six-view radiographic evaluation. Helical CT has been suggested as a replacement for the more traditional radiographic evaluation of the cervical spine in trauma victims. Evidence now exists to support that recommendation.
本研究的目的是确定对整个颈椎进行螺旋CT检查所需的时间。我们的研究对象包括156名创伤患者：其中100例患者在进行颅脑检查时同时接受了CT检查；其余56例患者仅接受了颈椎初步检查。
在进行颅脑CT检查时同时进行颈椎CT检查，使总体研究时间平均增加了12分钟。进行颈椎初步检查的平均时间为11分钟。这些时间约为六视图X线片评估所需时间的一半。有人建议用螺旋CT取代对创伤患者颈椎进行的更传统的X线片评估。现在有证据支持这一建议。
