Diagnostic Value of MR-Hysterosalpingography in Tubal Patency

Objective: To discuss the value of MR-hysterosalpingography(HSG) in diagnosing the tubal patency.Methods: A total of 20 infertile women were referred to conventional pelvic scanning by MRI and MR-HSG,and all subjects underwent conventional HSG under fluoroscopy 6 months averagely before MR-HSG.Standard axial,sagittal and coronal T2-weight and axial T1-weight sequences were acquired.A balloon catheter was placed into the uterine cavity and then flash 3D coronal MR scanning was performed,with the uterine injection of diluted Gadodiamide(1:100).Digital subtraction reconstruction was performed according to the data acquired.Results: The tubal patency in 20 women was successfully evaluated using MR-HSG,and the results were compared with those of conventional HSG.One case showed left interstitial fallopian tube occlusion under the conventional HSG,but showed patency under MR-HSG.Another case with bilateral fallopian tube occlusion and hydrosalpinx under conventional HSG showed only hydrosalpinx but no occlusion under MR-HSG.The third case with bilateral fallopian tube occlusion under X ray had only left side occlusion under MR-HSG.The results by the two methods were similar in the remaining patients.MR scanning on pelvis showed more clearly in pelvic organs,endometrial state,uterus malformation,hysteromyoma,and hydrosalpinx.Conclusion: Routine MRI scan combined with HSG can better display the fallopian tubes,ovaries,uterus and pelvic tissues,so it has a high clinical value in the diagnosis of infertility.
