磁共振子宫输卵管成像在不孕症诊断中的应用

Applicatioan of Magnetic Resonance Hysterosalpingography in Diagnosis of Women Infertility

目的:探讨磁共振子宫输卵管造影(MR-HSG)在不孕症诊断中的应用价值。方法:对24例女性不孕患者进行盆腔磁共振扫描和MR-HSG。常规MR扫描包括横轴位T1WI,横轴面和冠状面脂肪抑制T2WI;MR-HSG应用磁共振水成像技术(MRH),在MR磁体内通过导管向宫腔内注射0.9%生理盐水后,利用单次激发厚层投射(SS-FSE)技术进行子宫输卵管造影。结果:所有患者均能顺利进行MR-HSG检查,常规MRI可以很好地显示盆腔结构、子宫腔、黏膜、肌层及卵巢结构;MR-HSG表现为双侧输卵管阻塞者6例,输卵管单侧阻塞者9例,输卵管正常9例。结论:MR-HSG图像结合常规MRI能很好地显示输卵管、子宫、卵巢与盆腔结构,在不孕症的诊断中具有较高的临床应用价值。

Objective：To investigate the diagnostic value of magnetic resonance hysterosalpingography （MR-HSG） in diagnosis of women infertility.Methods：24 consecutive infertile women underwent MR-HSG and conventional MRI.The MR protocol consisted of axial T1-weighted imaging, axial/coronal T2-weighted imaging and T2WI with fat saturation.Single shot fast spin-echo （SS-FSE） technique was used in magnetic resonance hydrography （MRH）,after injected 15ml saline （0.9%） solution into the cavum uteri via a balloon catheter,MR-HSG was conducted.Results：Evaluation of pelvic anatomy,mucosa,myometrium,cavum uteri and ovaries was possible in all patients on the basis of T1WI、T2WI and T2WI with fat saturation.Of the 24 patients,9 involved unilateral fallopian tube occluded and 6 involved bilateral fallopian tubes occluded,while 9 were proved bilateral fallopian tubes patent.Conclusion：Conventional MRI and MR- HSG could visualize both the pelvic abnormality and Fallopian tube patency,which would be valuable for the diagnosis of women infertility.
