摘　　要：目的明确核磁共振成像下儿童脊髓圆锥末端位置。方法回顾性分析行腰骶椎核磁共振成像检查儿童,年龄1 d^15岁。以记数方式表示脊髓圆锥末端对应脊柱位置,将每一脊柱单元等分为上、中、下1/3,并分别用U、M、L表示,椎间盘作为一独立节段。将T12-U1/3记为0,T12-M1/3记为1,T12-L1/3记为2,T12-L1记为3,由上到下依次记数。将患儿分为不同年龄段:<1个月、1~5个月、6~11个月、1岁、2~4岁、5~9岁和10~15岁;按照性别将患儿分为男性组(M组)和女性组(F组),比较2组脊髓圆锥末端位置。结果本研究共纳入患儿231例,其中男性122例,女性109例,年龄为(4±4)岁。<1月、1~5月、6~11月、1岁、2~4岁、5~9岁和10~15岁患儿,脊髓圆锥末端位置对应记数分别为:7.3±2.0、7.3±2.3、6.4±1.8、6.5±2.6、5.4±2.2、5.5±1.8和5.0±1.8。M组和F组脊髓圆锥末端位置差异无统计学意义(P>0.05)。结论<1个月、1~5个月、6~11个月、1岁、2~4岁、5~9岁和10~15岁儿童脊髓圆锥末端位置对应记数分别为:7.3、7.3、6.4、6.5、5.4、5.5和5.0。Objective To determine the location of the conus medullaris termination(CMT)in children under the magnetic resonance imaging(MRI).Methods The children,aged 1 day to 15 yr,underwent MRI performed on the lumbosacral spine,were retrospectively analyzed.The CMT corresponding to the position of vertebral body was sequentially numbered.Each vertebral body was divided into upper(U),middle(M),and lower 1/3 unit(L),while the intervertebral disc was considered as an independent segment.From top to bottom of vertebral body,T12-U1/3 was marked as 0,T12-M1/3 was marked as 1,T12-L1/3 was marked as 2,and T12-L1 was marked as 3,respectively.The children including male group and female group were divided into different age groups:<1 month,1-5 months,6-11 months,1 yr,2-4 yr,5-9 yr and 10-15 yr.The children were divided into male group(M group)and female group(F group)according to gender,and the positions of CMT were compared.Results A total of 231 children were enrolled in this study,including 122 males and 109 females,aged(4±4)yr.The corresponding number for the position of CMT in children aged<1 month,1-5 months,6-11 months,1 yr,2-4 yr,5-9 yr and 10-15 yr was 7.3±2.0,7.3±2.3,6.4±1.8,6.5±2.6,5.4±2.2,5.5±1.8,and 5.0±1.8,respectively.There was no statistically significant difference in the position of CMT between group M and group F(P>0.05).Conclusion The corresponding number for the position of CMT is 7.3,7.3,6.4,6.5,5.4,5.5 and 5.0 in children aged<1 month,1-5 months,6-11 months,1 yr,2-4 yr,5-9 yr and 10-15 yr,respectively.
