MRI对妇科扭转性病变的诊断价值

The Diagnosis Value of MRI in Pedicle Torsion of Gynecological Disease

目的:探讨MRI对妇科扭转性病变的诊断价值。材料与方法:收集经手术病理证实的妇科蒂扭转患者资料11例,回顾性分析MRI与彩色多普勒超声征象,对比两者诊断蒂扭转的准确性。结果:11例患者,MRI明确诊断10例,漏诊1例,MRI能很好显示扭转蒂,部分呈典型漩涡征、悬挂征,同时还能评估肿块出血、坏死、输卵管扩张及盆腔积液等情况。彩色多普勒超声明确诊断4例,漏诊7例。两者诊断准确率差异有统计学意义(P<0.05)。结论:妇科扭转性病变有较特征的MRI表现,结合临床病史,MRI可对多数妇科扭转性病变作出正确诊断,具有较高的临床应用价值。

Purpose： To investigate the diagnostic value of MR imaging（ MRI） for pedicle torsion of gynecological disease. Materials and Methods： A total of 11 cases confirmed by surgery were underwent MRI and color doppler flow imaging（ CDFI） to analysize the accuracy of the two methods in the diagnosis of gynecological acute abdominal disease with pedicle torsion comparatively. Results： Of the 11 cases,10 cases were diagnosed pedicle torsion and one case was misdiagnosed by MRI,pedicle torsions were observed in ten cases on MRI obviously,some of them presented typical＂whirlpool sign＂,＂suspension sign＂,other MRI signs of gynecological disease with pedicle torsion had also occurred,such as mass bleeding,adnexal oviduct thickening display and pelvic cavity effusion,etc. 4 cases were diagnosed pedicle torsion and 7 case was misdiagnosed by CDFI. The accuracy rate of MRI were significant higher than that of CDFI（ P ﹤ 0. 05）. Conclusion： The pedicle torsion of gynecological disease have some MRI charateristic features,which is helpful for correct diagnosis combining with clinic presentation in most cases,MRI has a perfect clinical value for pedicle torsion of gynecological disease.
