The subject of this study was to define age-related and gender-dependent changes in MR features of the lacrimal gland.
MR images were retrospectively analyzed in 104 normal subjects aged 2-79 years to measure thickness and area of the lacrimal gland, its MR signal intensity ratio, and SD of the MR signal intensity profile.
Thickness and area of the lacrimal gland decreased with age in women (p < 0.001), but not in men. Furthermore, MR signal intensity ratio of the lacrimal gland showed an age-related increase in women (p < 0.001), but not in men. On the other hand, SD of the MR signal intensity increased with age in both women and men (p < 0.001).
These findings demonstrate that gender has a significant influence on lacrimal gland structure during development and aging.
本研究的主题是确定泪腺磁共振成像（MR）特征中与年龄相关以及与性别相关的变化。
对104名年龄在2至79岁的正常受试者的MR图像进行回顾性分析，以测量泪腺的厚度和面积、其MR信号强度比以及MR信号强度曲线的标准差。
女性泪腺的厚度和面积随年龄增长而减小（p < 0.001），男性则不然。此外，女性泪腺的MR信号强度比随年龄增长而增加（p < 0.001），男性则不然。另一方面，女性和男性的MR信号强度标准差均随年龄增长而增加（p < 0.001）。
这些发现表明，性别在发育和衰老过程中对泪腺结构有显著影响。
