Endometriosis:Diagnosis with MRI Imaging

目的 分析子宫内膜异位症的磁共振 (MRI)影像特征 .材料与方法 回顾性分析 5 1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 子宫增大 48例 ;T2WI及T1WI显示子宫有弥散分布的片状低信号区内夹杂斑点状高信号 30例 ;T2WI显示子宫低信号区内夹杂斑点状高信号 ,T1WI呈低信号 2 1例 .2 9个卵巢囊肿 ,T1WI及T2WI均呈高信号有 15个 ,T1WI呈高信号而T2WI呈低或等信号 5个 ,T1WI和T2WI均呈混杂信号 9个 .结论子宫内膜异位症的主要MRI表现 :(1)子宫内出现片状低信号区 ,同时夹杂斑点状高信号 ;(2 )

Objective To analyze the MRI features of endometriosis. Methods Endometriosis diagnosed by MRI in 51 cases were retropectivey studied. All were proved by surgery and pathology. Results Uterus enlarged in 48 cases , 30 cases show diffuse and low-intensity area accompanied by tiny high-intensity spots on both T2WI and T1WI; 21 cases show tiny high-intensity spots on T2WI and low-intensity on T1WI. 29 cysts in 24 cases, 15 showed high signal intensity on T1WI and T2WI ,5 as high on T1WI and as medium or low T2WI ,9 as mixed. Conclusions Diagnosing endometriosis in MRI depends on:(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, mainly with high or medium signal on both T1WI and T2WI in cyst.
