Radiology:号外!依靠MRI可以诊断多囊卵巢综合征啦!

2017-07-26 shaosai MedSci原创

多囊卵巢综合征(polycystic ovarian syndrome,PCOS)是育龄妇女较常见的内分泌症候群。1935年,Stein与Leventhal首先描述双侧卵巢肿大者伴不孕、多毛与肥胖等表现,称为Stein-Leventhal综合征。随着临床研究的深入,组织学上具有多囊卵巢伴无排卵和(或)多毛症的临床症候群范围不断扩大。1963年,Goldziether总结187篇共1079例PCOS

多囊卵巢综合征(polycystic ovarian syndrome,PCOS)是育龄妇女较常见的内分泌症候群。1935年,Stein与Leventhal首先描述双侧卵巢肿大者伴不孕、多毛与肥胖等表现,称为Stein-Leventhal综合征。随着临床研究的深入,组织学上具有多囊卵巢伴无排卵和(或)多毛症的临床症候群范围不断扩大。1963年,Goldziether总结187篇共1079例PCOS资料,发现其中有许多非典型病例,如无多毛,甚至有排卵功能。随着检测技术的发展,认识到多囊卵巢并非一种独特的疾病,而是一种多病因、表现极不均一的临床综合征。本研究为了探究基于MRI影像学诊断青年女性多囊卵巢综合征(PCOS)的结构性特征,并将结果发表在Radiology上。

本研究共纳入了110例自2006-2015年进行盆腔MR扫描的患者,该组包括40例高度怀疑PCOS的患者(雄激素过多症、月经稀发或闭经)、8例中度怀疑PCOS的患者(雄激素过多症)和7例轻度怀疑PCOS的患者(月经稀发或闭经)。对高度怀疑PCOS的青年女性的≤9mm的卵泡数(FPO)和≤5mm的FPO的确定(敏感性、特异性和ROC曲线下面积(AUC))、卵巢体积(OV)、球形指数、卵泡的外周分布特点和优势卵泡的缺失进行评价,并以健康志愿者组为参考标准进行两组间比较。两位放射科医生独立地对50例怀疑PCOS的青年女性进行检验以上诊断标准来评价可重复性(k值和内部相关系数(ICCs))。

结果为,除了球形指数和优势卵泡的缺失两项之外的其他标准与PCOS的可能性高度相关(P ≤ .05)。FPO-9 (0.78; 95% CI: 0.68, 0.87)、FPO-5 (0.73; 95% CI: 0.62, 0.83)和OV的AUCs (0.77; 95% CI: 0.68, 0.87) 均>0.5。而球形指数的AUC并不准确 (AUC, 0.58; 95% CI: 0.47, 0.70)。卵泡外周分布特点的敏感性和特异性分别为33% (95% CI: 19%, 49%)、 95% (95% CI: 85%, 99%); 对于优势卵泡的敏感性和特异性分别为 90% (95% CI: 76%, 97%) 、 27% (95% CI: 16%, 41%)。 OV的可重复性优秀 (ICC, 0.89), 优势卵泡缺失的可重复性良好(κ, 0.74), FPO-9 (ICC, 0.54) 和 FPO-5 (ICC, 0.61)的可重复性中等,卵泡外周分布特点的可重复性一般 (κ, 0.37)。

本研究表明,PCOS基于MR影像学最可靠的诊断标准为OV、FPO-9和卵泡外周分布特点;而这些标准的可重复性除了OV以外都是中等。
