对比3D—MRI与三维超声在先天性子宫畸形应用价值(1)
摘要:目的 对比3D-MRI与三维超声两种检查方法在先天性子宫畸形的价值。方法 选择在我院住院的子宫畸形患者41例,其中原发不孕10例,不良孕产史31例,分别行经阴道三维超声及3D-MRI检查,其结果与宫腔镜和 (或)腹腔镜检查结果对照。结果 在41例病例中,纵隔子宫共22例(其中完全性纵隔子宫10例,不全性纵隔子宫12例),双角子宫6例,双子宫双宫颈4例,单角子宫4例,幼稚子宫3例,弓形子宫2例,其中三维超声诊断符合率82.90%,3D-MRI诊断符合率97.60%,两者间差异有統计学意义。结论 3D-MRI较三维超声更能准确地分型诊断,同时提供客观的测量数据,指导手术方案的制订。

Abstract:Objective To compare the value of 3D-MRI and three-dimensional ultrasonography in congenital uterine malformations.Methods 41 patients with uterine malformations were enrolled in our hospital.Among them,there were 10 cases of primary infertility and 31 cases of adverse pregnancy.They were examined by transvaginal three-dimensional ultrasonography and 3D-MRI.The results with hysteroscopy and(or)laparoscopy results were compared.Results In 41 cases,there were 22 cases of mediastinal uterus(including 10 cases of complete mediastinal uterus,12 cases of incomplete mediastinal uterus),6 cases of bilateral uterus,4 cases of double uterine cervix,4 cases of uterine uterus,childish uterus 3 cases,arcuate uterus in 2 cases,including three-dimensional ultrasound diagnosis rate of 82.9%,3D-MRI diagnosis coincidence rate of 97.6%,the difference between the two was statistically significant.Conclusion 3D-MRI is more accurate than three-dimensional ultrasound diagnosis,while providing objective measurement data to guide the development of surgical programs.

先天性子宫畸形是女性不孕不育的常见原因,而子宫畸形的不同分型与其治疗方法有着直接的关系。因此,及时诊断子宫畸形并对其进行准确分型对临床的诊断和治疗都具有重要的指导意义[1]。三维超声及3D-MRI均可较好地显示子宫冠位从而判断子宫畸形,但两者间是否存在差异,相关横向对比评价较少,本文对经阴道三维超声、3D-MRI诊断先天性子宫畸形的结果进行比较,评价两种方法的诊断价值。
1资料与方法
1.1一般资料
回顾性分析2012年9月~2014年10月怀疑子宫畸形的患者41例,经宫/腹腔镜证实完全性纵隔子宫10例,不全性纵隔子宫12例,双角子宫6例,双子宫4例,残角子宫2例,单角子宫2例,还有3例无需手术的幼稚子宫和2例弓形子宫,年龄19~37岁,平均年龄(24.1±2)岁。就诊原因:原发不孕10例,不良孕产史31例。所有患者术前均行经阴道三维超声检查及3D-MRI检查。

1.2检查方法
1.2.1经阴道三维超声 应用GE E8三维实时超声诊断仪,使用三维容积探头,频率为5~9 MHz。常规行二维超声检查, 观察子宫的外形轮廓、宫腔形态及卵巢附件,注意宫旁是否有包块,若有包块观察其回声、血流及与子宫的关系。获取满意的二维超声图像后,嘱患者 屏住呼吸,启动3D/4D功能,调节容积取样框至能包括宫腔及宫颈全长,将容积边框靠近,尽量与子宫内膜平行,启动自动扫描,调整X、Y、Z轴使子宫内膜的三维图像清晰显示。然后冻结、存储。观察宫腔形态是否异常,测量相应数据,做出超声诊断。
1.2.2 3D-MRI 使用GE公司生产的1.5T HDx超导磁共振扫描仪,采用体部8通道相控阵线圈,常规扫描采用SE T1WI及T2WI序列,包括矢状面,层厚4 mm,层间距1 mm, Fov:320×320 mm。横断面,层厚4 mm,层间距1 mm,Fov: 320×320 mm及冠状面,层厚4 mm,层间距1 mm,Fov:320×320 mm。主要观察冠状面,观察宫底外形、子宫内膜及卵巢附件周围软组织 情况。3D FIESTA序列采用层厚3 mm,层间距-1.5 mm,FOV:400×400 mm,两位主治以上医师分别作出诊断,当结果不相符时,两者经讨论共同得到结论。, http://www.100md.com(杨琳 丁立 康敏 王世琦)
