摘要
目的:分析子宫内膜异位症的MRI影像特征。材料和方法:回顾性分析26例子宫内膜异位症的MRI影像特征,全部病例经手术及病理证实。结果:12例T_2WI显示子宫内大片低信号区,同时加杂斑点状高信号,10例T_1WI显示低信号区内加杂斑点状高信号,2例T_1WI显示均匀信号。19个附件囊肿,其中9个T_1WI和T_2WI均呈高信号,4个T_1WI呈高信号而T_2WI呈低或等信号,6个T_1WI和T_2WI均呈混杂信号。结论:诊断子宫内膜异位症的主要MRI依据:(1)子宫内出现片状低信号区,同时加杂斑点状高信号;(2)囊肿在T_1WI和T_2WI均为高信号,或以高中信号为主的混杂信号。
Purpose: To analyze the MRI features of endometriosis. Materials and methods: Endometriosis diagnosed by MRI in 26 cases were retrospectively studied. All were proved by surgery and pathology. Results: Diffuse and low-intensity area accompanied by tiny high-intensity spots on T2WI in 12 cases, similar intensity on T1WI in 10 cases, low-intensity on T1WI in 2 cases. 19 cysts were seen in 14 cases. Among them, 9 showed high signal intensity on T1WI and T2WI, 4 high on T1WI and medium or low on T2WI, 6 mixed intensity on both T1WI and T2WI. Conclusion: The MRI features of endometriosis were: (1) Local or diffuse low-intensity area accompanied by tiny high-intensity spots on both T2WI and T1WI in uterus. (2) High and mixed signal, on both T1WI and T2WI in cyst.
