Hysterosalpingography
Hysterosalpingography (HSG) is a fluoroscopic
X-ray study of a woman's uterus and fallopian
tubes. It involves insertion of a catheter into
the cervix and instillation of a water soluble
contrast material into the uterus and
fallopian tubes.
Any woman who is pregnant, or thinks she
might be, should let her doctor know before
proceeding with the exam.
What to expect during the HSG?
The obstetrician/gynecologist performs the
study with fluoroscopic assistance from the
radiologist. The study usually is completed
within 30 minutes.
While lying on the X-ray table the obstetrician/
gynecologist will place a speculum into the
vagina, clean the cervix, and then insert a
catheter into the cervix. The speculum is
then removed. Contrast material is then
slowly instilled to fill the uterine cavity,
fallopian tubes and peritoneal cavity. As
this occurs, fluoroscopic X-ray images are
taken. These images are promptly reviewed
and the catheter removed.
