摘要

目的 :研究正常恒河猴子宫的MRI表现。方法 :对 16只雌性恒河猴在生殖季节和非生殖季节分别行MRI检查并对子宫做观察和测量 ;同时随机选择生殖季节和非生殖季节猴各 3只剖腹直视下测量子宫各径线和计算体积。结果 :MRI轴位像示恒河猴子宫外形呈椭圆形

矢状位像略呈哑铃形。T1WI示宫体各层信号与盆壁肌肉信号相近 ;T2 WI示宫体肌层的信号高于宫颈

宫体可见 2～ 3层不同的信号带。增强扫描示子宫肌层及内膜呈均匀强化。不同季节（生殖季节和非生殖季节）子宫各径线均值和平均体积变化明显（P <0 .0 5 ） ;MRI测量值与直视下测量值比较

差异无显著性（P >0 .0 5 ）。结论 :MRI能很好地显示恒河猴子宫的形态、大小及其信号特征。

Abstract

Objective:To investigate MRI characteristics of normal rhesus uterus.Methods:Sixteen female rhesus were inspected in their breeding season and non-breeding season using MRI

in order to observe the shape and the MR signal characteristics of their uteri and to measure the size of the uteri;and the size of uteri was measured in 3 animals after laparotomy procedures in breeding season and non-breeding season

respectively.Results:On MRI

the shape of the uterus was elliptic in axial view and dumbbell shape in sagittal view in different season (breeding season and non-breeding season).The signal-intensity of the uterine body was similar to the pelvic muscle in T 1WI.In T 2WI

the signal-intensity of the uterine body muscle layer was higher than the uterine neck

and 2～3 different signal-intensity strips were observed in uterine body.On enhanced MRI

uterine cavity showed slightly low-signal-intensity

and uterine muscle layer and inner membrane showed homogeneous enhancement.The average size of the uteri was 4.9cm×2.6cm×1.9cm in breeding season

and 3.0cm×1.76cm×1.32cm in non-breeding season.There were significant differences between the average diameters and average sizes of the uteri in breeding season and that in non-breeding season ( P <0.05)

and there was no significant difference between the diameters and sizes determined by MRI and that measured under gross inspection( P >0.05).Conclusion:MRI could clearly display the shape and size and signal-intensity characteristics of the uterus

so it is an appropriate approach to guide and follow up HIFU (high intensity focused ultrasound) study.
