【摘要】 目的:通过测量正常人群海马及侧脑室颞角的线性指标,探讨海马形态相关线性指标的参考值。方法:通过磁共振成像(MRI)测量105名健康个体在设定的3个标准测量平面上两侧海马及侧脑室颞叶角的面积、高度和宽度,并进行左右侧和不同性别分组间的比较。结果:人脑两侧海马面积比较差异无统计学意义(P>0.05),两侧海马宽度(右侧>左侧)及高度(左侧>右侧)比较差异均有统计学意义(P<0.01)。两侧侧脑室颞角的面积、高度及宽度比较差异均无统计学意义(P>0.05)。男性和女性人群间海马及侧脑室颞角的测量值比较差异均无统计学意义(P>0.05)。结论:在标准测量平面上两侧海马宽度及高度存在差异性,提示海马及侧脑室颞角的线性测量指标参考值可作为相关疾病临床诊断依据。更多还原

【Abstract】 Objective To provide the standard morphological parameter values of hippocampal through linear measurement of the hippocampus and the temporal horn of the lateral ventricle in healthy subjects.Methods The areas,heights,and widths of the hippocampus and the temporal horn of the lateral ventricle were measured in 3standard planes on magnetic resonance images(MRI)in 105healthy subjects,and the comparisons between left side and right sides and between various gender groups were performed.Results The difference of the areas of the hippocampus between the two sides of brain had no significance(P>0.05).However,the differences of width(right side>left side,P<0.01)and heights(left side>right side,P<0.01)of the hippocampus between the two sides were significant.There were no significant differences of the widths,heights and areas of temporal horn of the lateral ventricle between the two sides(P >0.05).The difference of the measurement values of the hippocampus and the temporal horn between the male and the female had no significance(P > 0.05). Conclusion There are differences of the width and height of the hippocampus in standard planes between the two sides.The linear measurement standard values of the hippocampus and the temporal horn of the lateral ventricle obtained in standard planes will help the clinical diagnosis in related diseases.更多还原
