2、果单房、低张力形态、囊壁不强化、同侧卵巢显示及SL连续5个征象在POC组较OL、OC和OCA多见(P值均<0.05),诊断POC的敏感性、特异性和准确性分别为92.0%、45.5%和56.9%,76.0%、81.8%和80.4%,72.0%、66.2%和67.6%,64.0%、84.4%和79.4%,88.0%、90.9%和90.2%。POC组较小、囊液呈均匀水样信号,与OL及OCA组差异有统计学意义(P值均<0.05)。POC组较其余3组囊壁更薄(P值均<0.05)。结论单房、低张力形态、薄壁无强化、囊液均匀水样信号、同侧卵巢显示及SL连续为MRI诊
3、断POC的有价值征象,有助于与OC及OCA鉴别。关键词:卵巢冠囊肿;卵巢囊肿;卵巢囊腺瘤;磁共振成像DOI:10.3969/j.issn.1002-1671.2015.02.024中图分类号:R737.31;R445.2文献标志码:A文章编号:1002-1671(2015)02-0265-05MRIfeaturesfordifferentiatingparovariancystfromovariancystandcystadenomaZHANGDaqian,QIANGJinwei,CAISongqi,LIYongai(DepartmentofRadio
