摘　　要：目的:研究生殖季节和非生殖季节恒河猴正常子宫超声及MRI特征。材料和方法:用超声、MRI比较研究1 6只雌性恒河猴在生殖季节和非生殖季节子宫各径线值、体积以及影像学特征,并与剖腹直视下比较。结果:恒河猴子宫的各径线值、体积以及影像学特征随生殖季节变化明显;超声、MRI测定恒河猴子宫各径线值和体积呈线性相关,两种影像学方法的测量值与直视下测定值统计学分析无显著性差异(P >0 .0 5)。结论:超声、MRI能准确反映恒河猴子宫大小及影像学特征,可作为恒河猴生殖生理研究的一种有效评价手段。Purpose: To investigate the change of rhesus monkeys' uterus in various reproductive period with magnetic resonance imaging (MRI) and ultrasonography. Materials and Methods: The size and volume of uterine of sixteen monkeys in various stages of reproductive cycles were measured by MRI and ultrasonography respectively. These data was compared to what measured in larparotomy. Results: The size and volume of uteri varied drastically in different reproductive cycles; No significant difference was noticed in size or in volume between MRI and ultrasonography (P>0.05). Conclusion: Both ultrasonography and MRI could be used to monitor the uterus of rhesus monkey.
