摘　　要：目的探讨子宫腺肌症的低场(0.35T)MRI影像特点和鉴别诊断价值。方法回顾分析了14例经手术病理证实的子宫腺肌症的影像特征。结果弥漫性子宫腺肌症11例,T2WI结合带弥漫性增厚,厚度12.1～37.4mm,平均15.4mm,其中,8例患者子宫肌层低信号病灶内可见多发斑点状高信号影,典型者呈"飘雪征",3例患者的病灶呈均匀的低信号;局限性子宫腺肌症3例,结合带局限性增厚或外肌层结合带样信号灶,2例患者T2WI混杂有斑点状高信号。结论子宫腺肌症MRI表现具有明显特征性和鉴别诊断价值。Objective To discuss the utility of MR imaging with low field intensity（0.35 T） in the diagnosis and differential diagnosis of adenomyosis. Methods MRI findings of 14 patients with surgically and pathologically proved adenomyosis were analyzed retrospectively.Results Among 14 cases,the diffusive adenomyosis was found in 11 cases whose lesions presented the diffusive thickening of junctional zome on T2WI （ranging between 12.1 mm and 37.4 mm,mean thickening,15.4 mm）,of whom ,the lesions of 8 cases were hypointense on T2WI ,in which multiple-mottling hyperintense shadows could be found,while those in typical lesion were called as ＂floating snow sign＂,the lesions of 3 cases were homogeneous hypointense on T2WI .The remainder 3 cases were found to be the localized adenomyosis which presented as localized thickening of the junctional zone on T2WI or junctional zome-like signal foci of muscularis externa, of whom,the lesions of 2 cases mixed with mottling hyperintense on T2WI . Conclusion MRI findings of adenomyosis has obvious feature which is helpful to diagnose and differentiate this disease.
