HSG (Uterine Film)

Hysterosalpingography, known as HSG, is a radiologic procedure to examine the status of the uterine cavity and fallopian tubes.

It requires the injection of a radio-opaque material into the cervical canal and uterine tubes to examine them radiographically.

During HSG examination, this liquid, called as contrast agent, is filled slowly from cervix to inside by a special apparatus or thin cannulas. During this process, the filling of uterus and the flow of liquid from tubes are monitored on the screen of radiography device. Images are recorded at the most appropriate times, angles and status.

During HSG examination in total 5-6 images, first of which taken before the examination, 3-4 taken during the flow of contrast agent, and the last one showing the contrast agent distribution, should be taken. Less than four films may be insufficient in recognizing details. Except any requirement for an additional process or except special cases, more than six films are not preferred due to fact that it leads to radiation exposure without any further contribution to the diagnosis.

Radiographic images are printed and submitted together with its written report. Even though delivering the images on a CD seems to be a good option in terms of low cost and ease of transport, it is not preferred due to their problems of opening on different computers and lower image resolutions.
