摘要
目的評價MRI診斷子宮肌瘤的價値,方法綜合文獻28例及本院3例子宮肌瘤病例研究,共48個肌瘤。所有病例均採用FSET1WI、FSET2WI及其抑脂序列和FSET1WI增強掃描,對不同成像序列上的病灶信號特點及相關表現進行分析。結果48個肌瘤中,T1WI上表現分別爲低信號25個、等信號22個、高信號1個,T2WI上表現分別爲低信號36個、等信號9個、高信號3個,增強掃描所有病灶均出現程度不同的強化1但絕大多數病灶強化程度均低於子宮肌層組織。結論MRI診斷子宮肌瘤具有一定的特徵性,是目前最理想的檢查方法之一。
Objective To evaluate the MR imaging value in diagnosing uterine leiomyoma.Materials and Methods MR imaging was performed in 31 patients with 48 uterine leiomyoma combining 28 cases by literature reported and 3 cases in our hospital.Scan sequence were consisted of FSE T1-Weighted obtained before and after contrast media administration,FSE T2-Weighted and FS FSE T2-Weighted.MRI intensity signal and relative features of the uterine leiomyoma on different sequence were analyzed.Results 25 leiomyoma with hypointensity,22 leiomyoma with isointensity and 1 case with hyperintensity were shown on T1 weighted images;36 cases with hypointensity,9 cases with isointensity and 3 cases with hyperintensity were seen on T2 weighted images.After contrast media administration,all uterine leiomyoma enhanced with different intensity,most signal intensity was lower than that of myometrium.Conclusion MRI is characteristic in diagnosing uterine leiomyoma,and is one of most excellent methods at present.
