Hysterosalpingograpy (HSG Or Tube Test)


HSG is an X ray test which is done to see the outline of the shape of the uterus and to check if the fallopian tubes are blocked or open.

It is a minor procedure in which a special dye is injected that fills the uterus and then spills through the open fallopian tubes.

- The woman is made to lie on a bed that is positioned so that a x ray imager is above, that can take pictures during the procedure.

- The cervix is visualized then cleaned and then a cannula like devise is placed into the opening of the cervix.

- Then through this cannula a liquid dye that contains iodine is slowly injected to fill up the uterus.
