Hysterosalpingography (HSG) is a test to evaluate the uterine cavity and fallopian tubes, either structurally or to check tubal patency. Depending on the techniques used to perform this test, there are two types of HSG:
- Conventional hysterosalpingography: uses a radiopaque contrast medium that is introduced through the cervix in order to take images with an X-ray machine.
- Hysterosalpingosonography: uses a saline solution or a foaming gel that fills the uterus and tubes as it is introduced and allows them to be viewed by ultrasound.
