【摘要】 目的:分析子宫腺肌症的MRI表现及其诊断价值。方法:回顾性分析46例经手术病理证实的子宫腺肌症患者的MRI资料,并与术后病理学结果进行对照分析。结果:MRI检查结果与手术病理结果有高度的一致性。子宫腺肌症的MRI主要表现:①T2WI和翻转恢复序列图像显示结合带弥漫性或局限性增厚(12 mm),或者外肌层内见信号类似结合带的边界欠清的肿块;②T2WI病灶内出现点状或斑片状高信号灶,有时T1WI时也可出现;③T1WI增强扫描示病灶强化程度近似结合带;④子宫体积增大,轮廓光整;⑤T2WI和翻转恢复序列图像有时显示子宫带状分层结构(内膜、结合带)变形。结论:MRI对子宫腺肌症的定性和定位具有很高的诊断价值更多还原

【Abstract】 Objective:To study the MRI features and its diagnostic value of uterine adenomyosis. Methods: MRI features of 46 cases of uterine adenomyosis proved by surgery and pathology were reviewed and correlated with pathology manifestations. Results:MRI and pathology findings were highly consistent. The main MRI features of uterine adenomyosis were as follows: ①On T2WI and IR sequences, diffuse or focal widening (more than 12 mm) of junctional zone,or a focal mass with indistinct margin in the outer layer of myometriurn can be revealed and the signal intensity was similar to that of junctional zone;②High signal intensity spots appeared on T2WI, sometimes can also be seen on T1WI;③On contrast-enhanced T1WI,the signal intensity of adenomyosis was similar to that of juctional zone;④Uterine enlargement with well-defined contour;⑤ On T2WI and IR sequences, distortion of uterine Structures (endometrium, juctional zone) was shown. Conclusion: MRI is a very helpful modality in the diagnosis and localization of adenomyosis;更多还原
