The hysterosalpingography (HSG) is a medical imaging technique for studying the inside of the uterus, the uterus cavity, the lining, meaning the inner wall, and also the cervix. It also enables the visualization of the fallopian tubes, which connect the ovaries
and the uterus. HSG requires the injection of a substance opaque to X-rays
into the uterus. It is injected via a catheter
through the genital tract before taking x-rays. The images generated by the computer will be visible on a screen. This examination, among others, diagnose malformations of the reproductive tract or the presence of tumors
. However, it is less used since the advent of the ultrasound, but especially the hysteroscopy, which allows, via a mini-camera, direct visualization of the inside of the genital tract.
