摘要： 目的探讨外伤性椎间盘突出发生时间与CT值改变的相关性。方法分别对198例自伤性椎间盘突出疝出部髓核CT值(表示为A)和未疝出部髓核CT值(表示为B)进行测量,计算出二者的差值(即判定参数),分析判定参数与椎间盘突出时间的关系。结果判定参数与椎间盘突出时间具有相关性,其差异具有统计学意义,判定参数在-12～-40HU之间,平均为-25.8HU(AB)时,椎间盘突出时间在6至12个月;判定参数在37～289HU之间,平均为96.1HU(A>B)时,椎间盘突出时间在12个月以上。结论根据判定参数可判定外伤性椎间盘突出发生的大体时间。

Abstract: Objective To find out the relativity between the time when the traumatic prolapse of intervertebral disc occurred and the change of the CT numerical value. Methods The CT numerical value of the vertebral pulp of herniation (denoted as A) and the CT numerical value of the vertebral pulp without herniation (denoted as B) were measured in for 198 patients and analyzed the relation between this parameter and the time when the prolapse of intervertebral disc occurred. Results It′s found find out that there is relativity between the parameter and the time when the prolapse of intervertebral disc occurred,and this difference has the value for the statistics. when the parameter is at about -12 to-40 HU, the average value is-25.8 HU(AB),It can be determined the prolapse of intervertebral disc occurred more than 12 months ago. Conclusion The approximate time can be determined when the prolapse of interverterbral disc occurred by the paremeter.
