摘要
目的：通过MRI和VGStudio MAX 2.2软件对中国汉族成人颅内外相关径线及角度进行测量,分析其与性别、年龄、身高以及体质量的关系,并建立相应的直线回归方程.方法：用VGStudio MAX 2.2软件对MRI图像数据进行三维重建,直接用软件的测量工具对颅内外的相关径线及角度进行测量,并用SPSS20.0进行统计分析.结果：胼胝体横径A、鼻尖面角B、中脑水平横径C、侧脑室前角最大间距D、侧脑室三角区最大间距E在男性中的均值分别为72.22±6.41、173.07±8.28、89.58±4.46、127.34±8.16、33.32±3.25;在女性中的均值分别为68.67±5.18、117.99±5.03、36.08±4.46、52.56±6.66、31.39±2.55.其中测量指标除侧脑室前角最大间距值外,其余值男、女性别差异有统计学意义.在男性中,C值与身高,E值与体质量,女性中,B、C值与体质量,B、D值与年龄,均存在直线相关关系.结论：中国汉族成人颅内外径线及角度的测量在法医推断中有着重要的参考意义.
Objective： To measure the intracranial and extracranial lines and angles of Chinese aduks of Hart nationality by MRI and VG Studio MAX 2.2 software, to analyze their relationship with sex, age, height, and weight, and to construct the relative linear regression equations. Methods： The three-dimensional reconstruction of MRI data was built by VG Studio MAX 2.2 software. And then, the intracranial and extracranial lines and angles were measured, and analyzed with SPSS 20.0 software. Results： The mean values of line A （transverse diameter of corpus callosum）, angle B （angle through the nose tip）, line C （transverse diameter of the midbrain level）, line D（maximum distance of the anterior horn of lateral ventricle）, and line E （maximum distance of the trigone of lateral ventricles） in males were 72.22±6.41, 173.07±8.28, 89.58±4.46, 127.34±8.16, 33.32±3.25, and in females were 68.67±5.18, 117.99±5.03, 36.08±4.46, 52.56±6.66, 31.39±2.55, respectively. All results except line D showed a distinct difference between males and females. Besides, the height was statistically correlated with line C in males, and the weight was statistically correlated with line E in males and line C and angle B in females; and the age was statistically correlated with line D and angle B in females. Conclusion： The measurements of intracranial and extracranial lines and angles of Chinese adults of Han nationality plays an important role in the forensic inference.
