【摘要】 目的建立正常成人松果体MRI测量标准,并分析其性别差异及年龄变化规律。方法MRI扫描327例正常成人头颅,测量并分析松果体相关数据。结果松果体矢径女性(7.12±1.11)mm,男性(6.52±1.01)mm(女性>男性,P<0.05);松果体横径女性(5.72±0.98)mm,男性(5.38±1.07)mm;松果体高女性(4.38±0.43)mm,男性(4.03±0.62)mm;松果体体积女性(88.92±27.90)mm3,男性(74.35±23.62)mm3(女性>男性,P<0.05)。结论松果体矢径和体积女性大于男性,松果体体积性别差异出现在31~60岁。更多还原

【Abstract】 Objective To establish the parameter standard of pineal gland and discuss the changing rule of different groups by gender and age in health adults on MRI. Methods A total of 327 adult heads were scanned by using 3D MR sequences,pineal gland and its related structures were observed and analyzed.Results The length of the pineal gland was(7.12±1.11)mm in the female group,and(6.52±1.01) mm in the male group(female>male,P<0.05); The width of the pineal gland was(5.72±0.98) mm in the female group,and(5.38 ± 1.07) mm in the male group; The height of the pineal gland was(4.38 ± 0.43) mm in the female group,and(4.03±0.62) mm in the male group; The volume of the pineal gland in female group was(88.92±27.90) mm3,and(74.35±23.62) mm3 in the male group(female>male,P<0.05). Conclusions Length and volume of the pineal gland in female group were larger than in male group; Gender difference of the volume of the pineal gland occurred between 31 to 60 years old.更多还原
