摘　　要：目的 探讨子宫腺肌症的MRI表现及其诊断价值.方法 回顾性分析32例经手术和病理证实的子宫腺肌症病例的MRI资料,观察其MRI表现.结果 32例子宫腺肌症患者的MRI表现：①弥漫型子宫腺肌症21例,表现为子宫体积增大,轮廓光滑,结合带弥漫性增厚,与肌层分界不清,病灶在T1WI上呈等信号,9例内见点状高信号,在T2WI上呈低信号,内见散在点状高信号.②局限型子宫腺肌症11例,表现为子宫体部或底部局限性增大,相应部位结合带增厚,共发现18个病灶,在T1WI上呈等信号,5例内见点状高信号;T2WI上表现为与结合带信号相近的肿块影,7例内见点状高信号.③有12例合并其他妇科疾病,其中子宫肌瘤9例,卵巢囊肿3例.结论 MRI能对子宫腺肌症作出明确诊断,在其定性、定位及鉴别诊断中具有重要价值.Objective To explore the findings and diagnostic value of MRI in adenomyosis. Methods MRI features of 32 cases with adenomyosis confirmed by operation and pathology were analyzed retrospectively. Results Among the 32 patients：21 cases were diffuse adenomyosis, MR imaging findings included enlargement of uterus with well-circumscribed, widened uterine junction zone with ill defined margin between junction zone and myometrium. The adenomyosis lesions showed iso-signaI intensity on T1 WI with scattered hyper-intense loci in 9 cases and low signal intensity on T2WI with scattered hyper-intense foci in all cases; 11 cases were focal adenomyosis, MR imaging displayed localized myometrial masses with widening of junction zone,totally 18 lesions were found, the lesions were iso-signal intensity on T1 WI with scattered hyper-intense foci in 5 cases and low signal intensity similar to the junction zone on T2WI with scattered hyper intense foei in 7 cases; 12 cases were found to be complicated with other gynecological diseases, including 9 of hysteromyoma and 3 with ovarian cyst. Conclusion MRI is very useful in the diagnosis and differential diag nosis of adenomyosis.
