高原地区颅骨与核团大小的影像学相关性研究

The study of the relationship between skull and nuclei in plateau area

目的 研究高原藏汉族人群颅骨与脑内核团大小的相关性 ,从而为理想的手术效果提供客观依据。 方法 在西藏高原应用头部 CT对 10 4 8例颅骨和 5 2 7例脑内核团结构进行测量 ,并通过 SPSS10 .0统计软件进行分析。 结果 颅骨长度与丘脑长 (r=0 .174 ,P<0 .0 1)、豆状核长 (r=0 .2 0 0 ,P<0 .0 1)和尾状核头长 (r=0 .133,P<0 .0 1)呈显著正相关。颅骨宽度与丘脑宽 (r=0 .15 1,P<0 .0 1)、豆状核宽 (r=0 .2 0 7,P<0 .0 1)和尾状核头宽 (r=0 .10 1,P<0 .0 5 )呈显著性正相关。随着颅骨长宽值的增大 ,丘脑、豆状核和尾状核头长宽值也随之增大。颅骨长径每增加 10 mm,丘脑、豆状核和尾状核头长分别增加2 .2 18± 0 .170 m m、2 .2 2 2± 0 .172 m m和 1.136± 0 .111m m;颅骨宽径每增加 10 mm,丘脑、豆状核和尾状核头宽相应的增加1.2 2 2± 0 .12 9m m,1.2 0 3± 0 .171m m和 0 .6 94± 0 .112 m m。 结论 我们进行的颅骨与核团大小的对比研究 ,可以为术前靶点精确定位提供有益的帮助 。

Objective To study the relationship between skull and nucleus in high altitude in order to provide objective basement for ideal operative outcome. Methods We measured 1048 skulls and 527 nuclei using CT and analysed the data with SPSS 10.0 statistic software. Results There was on obvious positive relation between the length of the skull and the length of the thalamus( r=0.174,P <0.01), lenticular nucleus( r=0.200,P <0.01), and caudate nucleus( r=0.101,P< 0.05) respectively. With the increase of the skull length, the length of the thalamus, lenticular nucleus and caudate nucleus increased accordingly. When the skull length increased 10mm, the length of the thalamus, lenticular nucleus and caudate nucleus increased 1.222±0.129, 1.203±0.171, 0.694±0.112 respectively. Conclusion The comparative study between skull and nuclei in plateau area can offers benefit to pre operation precise orientation which leads to ideal operation outcome.
