摘要
目的探讨3.0TMRI对子宫平滑肌瘤与子宫腺肌瘤的鉴别诊断价值.方法回顾性比较分析经临床或病理证实的26例子宫平滑肌瘤与25例子宫腺肌瘤患者的3.0TMRI特征。结果 肌壁间子宫平滑肌瘤26例,共36个病灶,边界清晰,T2WI及T1WI显示均匀低信号32个;4个肌瘤变性,T2WI信号不均匀;11例增强扫描见均匀或不均匀强化,11例DWI呈等、低信号。子宫腺肌瘤25例,共28个病灶,呈T2WI低信号、T1WI等信号,边界不清。所有肿块内见到斑点状长T2信号;6例行增强扫描见病灶均匀强化,内散在点状低信号;6例行DWI示病灶呈低信号,内见散在点状高信号。结论 3.0TMRI对于精确鉴别子宫腺肌瘤与子宫平滑肌瘤具有很高价值。
Objective To investigate the differential diagnostic value of 3.0T MR in leiomyoma and adenomyoma.Methods MR images（3.0T） of 26 patients with leiomyoma and 25 patients with adenomyoma were analyzed retrospectively.All patients were proved pathologically or clinically.Results Totally 36 leiomyomas with clear boundary in 26 patients were well defined,32 lesions manifested as homogeneous low signal intensity on T1WI and T2WI.Inhomogeneous signal intensity on T2WI was observed in the other 4 lesions because of leiomyoma degeneration.Leiomyomas in 11 patients manifested as homogeneous or inhomogeneous enhancement,hypointense or isointense on DWI.Totally 28 adenomyomas with unclear boundary were displayed,manifested as low signal intensity on T2WI and isointense on T1WI.Spot-like signal intensity were observed on T2WI,homogeneous enhancement and spot-like low signal were notices in 6 patients with adenomyoma.Six patienys with adenomyoma underwent DWI,and the lesions manifested as low signal intensity and spot-like high signal intensity.Conclusion 3.0T MR has great value in differentiation diagnosis between adenomyoma and leiomyoma.
