A modified hysterosalpingography technique for the evaluation of ante- or retroverted uterine cavities

Objective - To describe a modified hysterosalpingography (HSG) technique developed to better visualize uterine cavities, consisting of adding an overhead radiograph to the routine examination performed with the radiographic tube angled 60 degrees. Materials and Methods - In addition to the standard views, a 60 degree angulated x-ray was taken either cranial or caudal, depending on the angulation of the uterus when the uterus was foreshortened in the standard projection. This modified protocol was utilized in a total of sixty consecutive infertile patients. Results - Of the 60 patients examined, a total of seven (12%) had intra-cavitary lesions identified that were not seen with the standard radiographs. All seven patients had confirmed small intracavity filling defects. Conclusion - When utilized in patients with anteverted and retroverted uteri, the described modified HSG technique can reveal additional findings that may not be seen on traditional HSG views.
