摘要
目的探讨多层螺旋CT(MSCT)对胸腰椎爆裂性骨折的临床诊断价值。方法以我院2013年3月-2015年6月收治的45例胸腰椎爆裂性骨折患者为研究对象,均行X线平片、MSCT平扫、MPR及VRT后处理,观察并比较不同检测方法对椎体骨折数目、附件骨折数目、椎管受累等显示情况。结果 MSCT轴位平扫椎体骨折个数检出率90.0%,附件骨折处数检出率86.8%,椎管分度准确度84.0%,均显著高于X线片的70.0%、64.8%、60.0%,差异有统计学意义(P<0.05)。MSCT轴位与VRT、MPR与VRT在椎体骨折个数、附件骨折处数、椎管受累方面比较差异显著(P<0.05)。MPR对附件骨折处数、椎管受累检出率明显高于MSCT轴位(P<0.05)。结论相比X线片,MSCT对椎体骨折节段、附件骨折及椎管受累显示更有优势,特别是MPR。
Objective To investigate the clinical diagnostic value of multi-slice spiral CT （MSCT） in thoracolumbar burst fractures. Methods 45 patients with thoracolumbar burst fractures treated in our hospital from March 2013 to Jtme 2015 were taken as the research objects. All the patients underwent X-ray plain film, MSCT plain scan, MPR and VRT postprocessing. The display of number of vertebral fi＇actures and accessory fractures, spinal canal involvement and so on by different detection methods were observed and compared. Results The detection rate of MSCT axial plain scan of the number of vertebral fractures （90%）, of accessory fractures （86.8%） and the accuracy of vertebral canal indexing （84.0%） were significantly higher than those of X-ray film （70.0%, 64.8%, 60%） （P〈0.05）. The differences of MSCT axial position and VRT, MPR and VRT in number of vertebral fractures, the number of accessoW fi＇actures, spinal canal involvement were significant（P〈0.05）. The detection rates of MPR in the number of accessory fractures and spinal canal involvement were significantly higher than those of MSCT axial position （P〈0.05）. Conclusion Compared with X-ray film, MSCT has more advantages on the seglnents of vertebral fractures, accessory fractures and spinal canal involvement, especially MPR.
