Three-dimensional dynamic MR hysterosalpingography: A preliminary

The aim of this study was to evaluate the feasibility of three-dimensional dynamic MR hysterosalpingography (3D MR HSG) for visualization of the cavum uteri and demonstration of bilateral fallopian tube patency as an alternat ive to conventional hysterosalpingography. Five infertile female patients u nderwent 3D dynamic MR HSG prior to conventional hysterosalpingography. The MR protocol consisted of axial T1-weighted spin-echo (SE), axial/coronal T 2-weighted fast SE (FSE), and 3D MR angiography sequences before, during, a nd after injection of a diluted gadolinium solution into the cavum uteri vi a a balloon catheter. Positioning of the catheter was feasible in all patie nts. In one patient the catheter slipped out during MRI and in one patient the catheter was placed far in the cavum uteri. In three patients catheter position was optimal at the level of the cervical canal. Evaluation of pelv ic anatomy, myometrium, and ovaries was possible in all patients on the bas is of T1-weighted SE and T2-weighted FSE. Three-dimensional visualization o f the dilated cavurn uteri was possible in four patients. In these four pat ients 3D MR HSG also proved bilateral fallopian tube patency which was conf irmed in each patient by conventional hysterosalpingography. Three-dimensio nal MR HSG is feasible and further research should be done to determine if this technique can evolve into an alternative technique to conventional hys terosalpingography with the advantages of no radiation and additional visua lization of the uterus wall and ovaries.
