摘　　要：[目的]测量L_(4/5)椎间隙影像参数,并分析其相关因素。[方法]收集2013年1月~2014年6月在本院行腰椎MRI检查的患者,共269人符合纳入标准,列入本研究,测量L_(4/5)椎间高度、终板长度和椎间高度指数。[结果] 269例中,男137例,女132例。将其按年龄分为三组:青年组(20~40岁),中年组(40~60岁),老年组(60岁以上)。各年龄组的性别构成差异无统计学意义(P>0.05)。各年龄组男性的椎间高度均大于女性,其中,中年组和老年组两性别间的差异有统计学意义(P<0.05);各年龄组男性的终板长度均小于女性,但差异均无统计学意义(P>0.05)。各年龄组男性的椎间高度指数均显著大于女性(P<0.05)。各年龄组间比较,男女两性别的青年组与中年组之间椎间高度、终板长度和椎间高度指数的差异无统计学意义(P>0.05),但是老年组与青年和中年组间上述指标差异均有统计学意义(P<0.05)。相关性分析显示,年龄与椎间高度呈负相关(r=-0.412,P<0.001),年龄与终板长度呈正相关(r=0.197, P=0.037),年龄与椎间高度指数呈显著负关相(r=-0.588, P<0.001)。相比之下,年龄与椎间高度指数相关性的r值最大。[结论] 60岁以前,L_(4/5)椎间高度随着年龄的增长而增大,但在60岁以后,L_(4/5)椎间高度显著下降,椎间高度指数可更好地反映L_(4/5)的年龄变化与性别间差异。[Objective] To measure the imaging parameters of the L_(4/5) intervertebral space and analyze their correlation with gender and age. [Methods] Among the persons who had lumbar MRI examinations performed in our hospital from January 2013 to June 2014, a total of 269 who met the inclusion criteria were enrolled in this study. The L_(4/5) intervertebral height, endplate length and intervertebral height index were measured and analyzed. [Results] Of 269 persons, 137 were males and 132 were females. They were divided into three groups according to age: the youth group(20~40 years old), the middle-aged group(40~60 years old), and the elderly group(over 60 years old),with no statistically significant differences in the gender among age groups(P>0.05). The male had greater intervertebral height than the female in all the age groups, which was not statistically significant in the youth group, whereas statistically significant in the middle-aged group and the elderly group(P<0.05). The male had smaller endplate length than the female in all age groups but there was no difference between the two genders in any age groups(P>0.05). The male had significantly greater intervertebral height index than the female in all the age groups(P<0.05). In term of comparison among age groups, intervertebral height, endplate length and intervertebral height index were of no significant differences in both the male and female between the youth group and the middle-aged group(P>0.05), whereas became statistically significant between the elderly group and the youth group or the middle-aged group(P<0.05). As results of correlation analysis, the age was negative correlation with intervertebral height(r=-0.412, P<0.001), and intervertebral height index(r=-0.588, P<0.001), whereas was positively correlated to endplate length(r=0.197, P=0.037). By contrast, the correlation between age and intervertebral height index got the largest r value. [Conclusion] Before the age of 60, the intervertebral height of L_(4/5) increases with age, but after that th
