Hysterosalpingography: technique and applications.

Hysterosalpingography (HSG) remains an important radiologic procedure in the investigation of infertility and has become a commonly performed examination due to recent advances of reproductive medicine. HSG demonstrates the morphology of the uterine cavity, the lumina, and the patency of the fallopian tubes. In this review article, we present the technical parameters of the examination, indications, contraindications, and possible complications of HSG. We also illustrate a variety of abnormalities of the uterus and fallopian tubes that can be detected accurately with HSG. We believe that, with the increased demand for HSG, radiologists should be familiar with HSG technique and the interpretation of HSG images.
