目的获取正常人群的环池CT测量值,为临床研究工作提供基础形态学资料。方法选择正常人群颅脑CT图像500例,分为10～20岁、21～30岁、31～40岁、41～50岁、51～60岁五个年龄组进行环池翼宽度测量。结果各组环池两翼宽度差异无显著性;各组间环池左翼宽度差异无显著性;右翼宽度差异无显著性;10～60岁环池两翼宽度值:左翼(3.01±0.35)mm,右翼(3.00±0.34)mm,两翼(3.00±0.35)mm。结论环池左右两翼宽度的CT测量值无明显差异,环池宽度CT测量值在各年龄组间无明显差异,研究环池翼宽度动态变化对脑受压的基础参考标准应以3 mm为宜。
Objective To obtain the circumferential pool CT measurements of normal population and provide basic morphological data for clinical research. Methods The brain CT images of 500 normal subjects were divided into 10 ~ 20 years old, 21 ~ 30 years old, 31 ~ 40 years old, 41 ~ 50 years old, 51 ~ 60 years old. Results There was no significant difference in width between the two limbs in each group. There was no significant difference in the left wing width between the groups and no significant difference in the width of the right wing between the groups. The widths of both wings in the 10 ~ 60 year old group were left (3.01 ± 0.35) mm, right (3.00 ± 0.34) mm, both wings (3.00 ± 0.35) mm. Conclusion There is no significant difference in the CT measurements of the width of the left and right cuffs. The measurement of cuff width CT has no significant difference among all age groups. It is appropriate to study the dynamic change of cuff width on the basis of 3 mm .
