摘　　要：目的　探讨低场MRI对子宫腺肌症的诊断价值。方法　回顾分析 18例经手术病理证实的子宫肌腺症低场MR影像征象。结果　弥漫性子宫腺肌症 15例 ,T2 WI及脂肪抑制像示结合带弥漫性增厚 ,厚度为 12 .0～ 3 2 .6mm ,平均 16.2mm ,其中 11例患者子宫肌层内低信号区内夹杂斑片状高信号影 ,典型者呈“飘雪征” ,4例为较均匀的低信号。T1WI上 6例子宫肌层内见少许斑点状高信号。局限性子宫腺肌症 (腺肌瘤 ) 3例共 4个病灶 ,病灶与周围组织分界不清。T2 WI及脂肪抑制成像上示类圆形或不规则形低信号或低信号内夹杂斑点状高信号 ,T1WI上 2个病灶内见斑点状高信号。结论　低场MRT2Objective To investigate the diagnostic value of low field MRI for adenomyosis. Methods MRI features of adenomyosis pathologically proved in 18 cases were retrospectively analysed.Results 15 cases were diffusive adenomyosis,the junctional zones of uterus were exteusive thickened to 12.0～32.6 mm,mean 16.2 mm,diffusive high signal intensity distributed over in myometrium which was low signal intensity in 11 cases,it was typical “snowing sign”,lower signal intensity in the myometrium in another 4 cases on T 2WI and fat-suppression imaging. A little high signal intensity was found in 6 cases on T 1WI. 3 cases were focal adenomyosis(adenomyoma), 4 lesions totally. The adenomyoma’s boundaries were not distinct and their shapes were roundish or irregular. The lesions were low signal intensity or diffusive high signal intensity distributed in the low signal intensity fields on T 2WI and fat-suppression imaging. A little high signal intensity was found in 2 lesions on T 1WI. Conclusion T 2WI and fat-suppression imaging of low field MRI are very useful techniques of the diagnosis of adenomyosis.
