目的 :观察子宫腺肌症的MRI表现,并与病理学进行对照分析。方法 :选择我院在2015年3月~9月诊治的子宫腺肌症患者45例进行MRI扫描诊断,所有患者的疾病均经过手术病理证实,对患者进行矢状面T1WI、T2WI、T1和T2频谱预饱和翻转恢复序列扫描,必要时进行横断面和冠状面扫描,观察患者的MRI表现。结果 :本次检查中24例弥散型子宫腺肌症,T2WI表现为子宫结合带增厚,4例呈现均匀的低信号,其余病变内散装的点伴有高信号;局限型子宫腺肌症20例,在T2WI上表现为肌层内不规则肿块,与结合带有相似的低信号,少部分病灶点带有高信号,MRI显示的弥散增厚结合带和局限性低信号在病理学上表现为异位内膜岛周围平滑肌增生肥大,在T2WI为高信号的内膜岛在T1WI上表现为高信号出血的内膜岛,本次MRI检测有一例被误诊为子宫肌瘤。结论:MRI检查是当前诊断子宫腺肌症最为准确的无创方法,最佳的扫描序列为T2W1,与其他扫描序列相结合能够提升准确率。
Objective: To observe the MRI findings of adenomyosis and compare it with the pathology. Methods: Forty-five patients with adenomyosis diagnosed and treated in our hospital from March to September in 2015 were diagnosed by MRI. All the patients were confirmed by surgery and pathology. The patients underwent T1WI, T2WI, T1 and T2 Spectral pre-saturation inversion recovery sequence scan, if necessary, cross-sectional and coronal scan to observe the patient’s MRI findings. Results: In this study, 24 cases of diffuse adenomyosis showed T2WI with thickening of the uterine junction, 4 cases showed a uniform low signal, the rest of the lesions in the bulk of the points with high signal; localized adenomyosis 20 For example, T2WI manifested as irregular intramuscular mass, with binding with a low signal, a small part of the lesion with high signal, MRI showed thickening of the combination of thickening and the limitations of low signal pathology in the performance It is a neointima island with high signal hemorrhage on T1WI, which is hyperplastic and hypertrophy around the ectopic endometrial island. One case of misdiagnosis as uterine fibroids was diagnosed on MRI. Conclusion: MRI is the most accurate and noninvasive method for the diagnosis of adenomyosis. The best scanning sequence is T2W1, which can improve the accuracy with other scanning sequences.
