子宫肌瘤病理特点与低场MRI表现对照分析

Correlative analysis of pathology characteristic and low-field MRI imaging in patients with uterine leiomyoma

目的探讨子宫肌瘤病理改变与低场MRI表现的相关性。方法回顾性分析58例经手术、病理证实的子宫肌瘤低场MRI表现。结果 58例低场MRI共发现子宫肌瘤103个,手术病理证实108个,MRI漏诊率为4.6%。子宫肌瘤低场MRI T2WI均显示低信号最具特征。肌瘤变性MRI平扫可表现为T2WI信号稍高且不均匀。病理显示子宫肌瘤大部分合并内膜增生。结论依据低场MRI影像特征能够准确诊断子宫肌瘤,并能反映肌瘤病理特点。

Objective To explore the relationship between the features of low-field MRI and pathological changes in the patients with uterine leiomyoma. Methods Low-field MR/manifests of 58 patients with uterine leiomyoma were analyzed retrospectively. All patients were verified by the pathology after surgery. Results 103 lesions of myomata were found by low-field MR/and 108 lesions were found by pathology in 58 patients. The missed diagnosis rate of MRI was 4.6%. The characteristic of uterine leiomyoma was low signal on T2WI. The lesions of leiomyoma degeneration showed slight high signal and was heterogeneously. The pathology showed that most uterine fibroids were accompanied with intimal proliferation. Conclusion According to characteristics of low-field MR/images can accurately diagnose uterine fibroids, and can reflect pathological characteristics of fibroids.
