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.
