目的探讨子宫内膜癌在MRI影像上表现特征。方法回顾性分析52例经手术组织病理证实的子宫内膜癌患者的MRI影像资料。结果 MRI诊断子宫内膜癌Ⅰa期17例,Ⅰb期18例,Ⅱ期11例,Ⅲ期5例,Ⅳ期1例,与组织病理结果进行对照,诊断Ⅱ,Ⅲ,Ⅳ期的特异度、敏感度均为100%,诊断Ⅰ期的敏感性、特异性分别为82.35%,77.78%;52例患者MRI显示子宫内膜不同程度增厚35例,结合带不完整24例,宫外转移4例;与组织病理结果进行对照,MRI诊断符合率为82.69%(43/52)。结论 MRI可较好显示子宫内膜癌浸润情况,可为子宫内膜癌的临床分期、诊断、治疗提供影像依据。
Objective To investigate the imaging features of endometrial carcinoma on MRI. Methods MRI data of 52 patients with endometrial carcinoma confirmed by histopathology were retrospectively analyzed. Results MRI diagnosis of endometrial carcinoma in 17 cases of stage Ⅰ a, 18 cases of stage Ⅰ b, 11 cases of stage Ⅱ, 5 cases of stage Ⅲ, 1 case of stage Ⅳ, and histopathological findings were compared to diagnose the specificity of stage Ⅱ, Ⅲ, Ⅳ, Sensitivity was 100%, the sensitivity of the diagnosis of stage Ⅰ, specificity were 82.35%, 77.78%; 52 cases of MRI showed endometrial thickening of varying degrees in 35 cases, with incomplete band 24 cases, extrauterine metastasis 4 Cases; compared with histopathological findings, the coincidence rate of MRI diagnosis was 82.69% (43/52). Conclusion MRI can better show the infiltration of endometrial cancer, endometrial cancer for clinical staging, diagnosis and treatment provide the basis for the image.
